Demuestra las funciones trigonométricas de 45o a partir de un cuadrado con longitud de lado igual a 1.
The most appropriate choice for trigonometric function will be given by -
sin 45° = [tex]\frac{1}{\sqrt{2} }[/tex]
cos 45° = [tex]\frac{1}{\sqrt{2} }[/tex]
tan 45° = 1
cot 45° = 1
sec 45° = [tex]\sqrt{2}[/tex]
cosec 45° = [tex]\sqrt{2}[/tex]
What are trigonometric functions?
Trigonometric functions are those functions which shows the relationship between side and angle of a right angled triangle.
There are six trigonometric functions-
[tex]sin \theta, cos\theta, tan\theta, cot\theta, sec\theta, cosec\theta[/tex]
[tex]sin \theta[/tex] = [tex]\frac{Perpendicular}{Hypotenuse}[/tex]
[tex]cos\theta[/tex] = [tex]\frac{Base}{Hypotenuse}[/tex]
[tex]tan\theta[/tex] = [tex]\frac{Perpendicular}{Base}[/tex]
[tex]cot\theta[/tex] = [tex]\frac{Base}{Perpendicular}[/tex]
[tex]sec\theta[/tex] = [tex]\frac{Hypotenuse}{Base}[/tex]
[tex]cosec\theta[/tex] = [tex]\frac{Hypotenuse}{Perpendicular}[/tex]
Here,
The diagram of the square has been attached with this answer
∠ABC = 90° [Side of a square is 90°}
∠BAC = [tex]\frac{90}{2}[/tex]
= [tex]45[/tex]°
Side of square = 1 unit
Length of diagonal of a square = [tex]\sqrt{2}[/tex] [tex]\times[/tex] side
= [tex]\sqrt{2}[/tex] [tex]\times[/tex] [tex]1[/tex]
= [tex]\sqrt{2}[/tex] units
From [tex]\Delta[/tex] ABC,
sin 45° = [tex]\frac{Perpendicular}{Hypotenuse}[/tex]
= [tex]\frac{BC}{AC}[/tex]
= [tex]\frac{1}{\sqrt{2} }[/tex]
cos 45° = [tex]\frac{Base}{Hypotenuse}[/tex]
= [tex]\frac{AB}{AC}[/tex]
= [tex]\frac{1}{\sqrt{2} }[/tex]
tan 45° = [tex]\frac{Perpendicular}{Base}[/tex]
= [tex]\frac{BC}{AB}[/tex]
= [tex]\frac{1}{1}[/tex]
= 1
cot 45° = [tex]\frac{Base}{Perpendicular}[/tex]
= [tex]\frac{AB}{BC}[/tex]
= [tex]\frac{1}{1}[/tex]
= 1
sec 45° = [tex]\frac{Hypotenuse}{Base}[/tex]
= [tex]\frac{AC}{AB}[/tex]
= [tex]\frac{\sqrt{2} }{1}[/tex]
= [tex]\sqrt{2}[/tex]
cosec 45° = [tex]\frac{Hypotenuse}{Perpendicular}[/tex]
= [tex]\frac{AC}{BC}[/tex]
= [tex]\frac{\sqrt{2} }{1}[/tex]
= [tex]\sqrt{2}[/tex]

There are thirty three students in the chess club. There are five more boys than girls in the club. Write and solve a system of equations to find the number of boys and girls in the chess club.
There are 14 girls and 19 boys in the chess club.
Step-by-step explanation:Let x be girls and y be boys in the chess club. First, we need to write the system.
We know there are 33 students in total.
x + y = 33
We also know there are five more boys than girls in the club.
x + 5 = y
Here is our system of equations and the solving process:x + y = 33
x + 5 = y
First, we will solve for y with substitution:
x + y = 33
x + (x + 5) = 33
2x = 28
x = 14
Now, we will plug in this x-value:
x + y = 33
(14) + y = 33
y = 19
There are 14 girls and 19 boys in the chess club.

What are Tangents?
A line that only touches a circle or an ellipse at one point is said to be divergent in geometry. If a line contacts a curve at point P, that point is referred to as the point of tangency. In other words, it is described as the line that, at that particular location, indicates the slope of a curve. The following methods can be used to find the tangent equation in differential geometry:
As we are aware, the gradient of the curve at any given location on the curve is equal to the gradient of the tangent to the curve. The following is how to determine the tangent equation of the curve y = f(x):
Utilizing the differentiation principles, determine the gradient function's derivative.
To determine the tangent's gradient, the derivative should be changed to include the provided point's x-coordinate
Find the tangent equation by substituting the provided coordinate point and the gradient of the tangent into the straight-line equation (in a slope-point formula).
Circle's Tangent
A closed, two-dimensional form, a circle is also a curve. The radius of the circle or the line from the center O to the point of tangency is always vertical or perpendicular to the tangent line AB at P, i.e., OP is perpendicular to AB as illustrated in the accompanying picture.
Geometric Tangent
Here, "AB" stands for the tangent, "P" for the point of tangency, and "O" for the circle's center. The OP is the radius of the circle.

Which of the following functions has an amplitude of 4 and a phase shift of pi over 4
The cosine function that has an amplitude of 4 and a phase shift of pi over 4 is given by:
f(x) = 4cos(2x - π/4) + 4.
How the cosine function is defined?The cosine function is defined as follows, considering it's coefficients:
y = acos(bx - c) + d.
The meaning of the coefficients is given as follows:
Coefficient a is the amplitude of the cosine function.Coefficient 2π/b gives the period of the cosine function.Coefficient c gives the phase shift of the cosine function.Coefficient d gives the vertical shift of the cosine function.In this problem, we want an amplitude of 4, hence coefficient a has a value of:
a = 4.
We also want a phase shift of π/4, hence the coefficient c has a value of:
c = π/4.
Among the given options, the one that gives a cosine function with the desired amplitude and phase shift is:
f(x) = 4cos(2x - π/4) + 4.

What are Trigonometric Identities?
Trigonometric Identities are equalities that utilize trigonometry functions and hold true for all variables in the equation. There are several trigonometric identities relating to the side length and angle of a triangle.
Given that the value of tan(x) = -4/3 and x is in quadrant 2.
In order to find the value of cos(2x), we can use the trigonometric identity of cos(2x), therefore, for cos(2x) we can write,
\cos(2x) = \dfrac{1-\tan^2(x)}{1+\tan^2(x)}cos(2x)=
1+tan

Since the value of tan(x) is known, substitute the value in the identity,
\begin{gathered}\cos(2x) = \dfrac{1-(-\frac{4}{3})^2}{1+(-\frac{4}{3})^2}\\\\\cos(2x) = \dfrac{1-(\frac{16}{9})}{1+(\frac{16}{9})}\\\\\end{gathered}

cos(2x) = (-7/9) × (9/25)

The length of metal flashing needed to be purchase is [tex]1\frac{5}{8}[/tex] feet's.
How to find the length of feet he needs to purchase?He needs 6 ½ feet of metal flashing to complete a household project.
He has two small pieces measuring 3 1/8 feet and 1 3 / 4 feet.
Therefore, the length of metals for him to purchase can be calculated as follows;
The length he has = 3 1 / 8 + 1 3 / 4
The length he has = 25 /8 + 7 / 4
The length he has = 25 + 14/ 8
The length he has = 39 / 8 feet

How to calculate the fraction?It should be noted that a fraction is simply used to represent the numbers that aren't whole.
Based on the information given, the fraction is illustrated as:
= - 1 3/4 - (-8 1/3) - (- 4 1/4)
Note that (-) × (-) = +
Therefore,
= - 1 3/4 - (-8 1/3) - (- 4 1/4)

The given equation is 11kx+13kx = 6
To solve this equation first we have to take x as common and rearrange the equation, so we can group the like terms together
x(11k+13k) = 6
Add the like terms in the equation
x(24k) = 6
Move 24k to the right hand side of the equation
x = 6/(24k)
Here we have to simplify the value of x, for that we have to divide 6 by 24k in the equation
