Show an example of how to evaluate a trigonometric function using reference
angle (without a calculator/ you may use left hand rule or unit circle)
Answer:
[tex]\cos(150) = -\frac{\sqrt 3}{2}[/tex]
Explanation:
An example is as follows;
Using reference angle, evaluate [tex]\cos(150)[/tex]
Solution:
We have: [tex]\cos(150)[/tex]
150 degrees is in the second quadrant, and it makes 30 degrees (i.e. 180 - 150) with the x-axis.
This implies that, cos(150) has the same magnitude as cos(30);
The only difference in the values is the sign; because
30 degrees is in the first quadrant where all functions are positive150 degrees is in the third quadrant where all cosine is negativeSo, we have:
[tex]\cos(150) = -\cos(30)[/tex]
-----------------------------------------------
[tex]\cos(30) = \frac{\sqrt 3}{2}[/tex]
-----------------------------------------------
[tex]\cos(150) = -\frac{\sqrt 3}{2}[/tex]
Read the excerpt from the story Winter Driving:
(3) "Yes, that's a good idea," Mina replied. "You have a long drive ahead of you, and it looks like the snow is not going to stop anytime soon. You don't want to get stuck anywhere on the roads, that would be even worse," Mina said worriedly as she walked Jesper to the door and handed him his jacket, which had been hanging on the coat rack.
(4) "Thank you so much for your hospitality, Mina. Keep in touch, and I will see you again soon." He hugged her goodbye and waved to the rest of the group before heading out the door. He took the elevator down to the main floor of the apartment building and walked to his car.
How do the events in paragraphs 3 and 4 contribute to the reader's understanding of Mina's feelings toward Jesper?
A By saying to Jesper that the snow isn't going to stop for a long time, Mina shows that she thinks Jesper is being silly by driving in the bad conditions.
B By walking him to the door and saying that they shouldn't wait so long to get together again, Mina shows that she enjoyed the visit with Jesper.
C By saying that Jesper has a long drive and that the snow isn't going to stop for a long time, Mina shows that she wants Jesper to stay longer.
D By walking him to the door and saying that they shouldn't wait so long to get together again, Mina shows that she hopes Jesper doesn't come back.

Answer:
I like the fact that am an inspiration to many people.
I like the fact that am not following the rat race and started taking risks and following my passion.
No matter how angry or sad I am, within an hour, or even less that, am again back to my normal state.
I like how I am willing to take risks, walk the extra mile, adapt myself to new situations and embrace my failures and challenges.
I can sense when people are feeling awkward or feeling left out in a group, I make sure that I make them feel comfortable and include them actively in the conversation or whatever we were doing.
My desire to learn endless things. Curiosity is the thing which keeps me going.
I listen. I listen a lot more than I talk.
I do charity, I help people, but am even proud to say that I don't yell publicly that I helped somebody, because if you do so, you are not doing a charity.
I like the sense of humour I have. The little sarcasm in my tone, makes me like myself even more. Haha.
I am not dependent on anyone for anything. I am happy to eat alone in a restaurant, or go out for a movie alone or even travel alone. Love yourself, it will be very helpful during stressful times.
I put my family, my friends above my work.
I can laugh on myself. When someone makes a joke on me and if it's funny and the truth, I do not get triggered and laugh at myself. Even when I trip down while walking or running, I have a good laugh, and by doing that, you will not at all feel awkward in front of the public at that moment.
I stopped caring what others think of me, or my interest in music or sport or anything.
I give real good hugs and I can be your 2 am conversation partner.
I like my sense of style.

Answer:
Umm Okay
Explanation:
determine the ........ of y= 4sin2x
o Amplitude
o Period
o Intercepts
o Maximum
o Minimum
Answer:
Amplitude: [tex]A = 4[/tex]
Period: [tex]\tau = \pi[/tex]
Minimum: -4
Maximum: 4
Intercepts: [tex]x = \frac{1}{2}\cdot [0 \pm \pi \cdot n][/tex], [tex]\forall \,n\in \mathbb{N}_{O}[/tex]
Explanation:
The expression described on statement is a sinusoidal formula, whose expression is of the form:
[tex]y = A\cdot \sin \left(\frac{2\pi\cdot x}{\tau}\right)[/tex] (1)
Where:
[tex]x[/tex] - Independent variable.
[tex]y[/tex] - Dependent variable.
[tex]A[/tex] - Amplitude.
[tex]\tau[/tex] - Period.
By direct comparison, we calculate the amplitude and period:
Amplitude
[tex]A = 4[/tex]
Period
[tex]\frac{2\pi}{\tau} = 2[/tex]
[tex]\tau = \pi[/tex]
Minimum and Maximum
The sine is a bounded function between -1 and 1, meaning that sinusoidal formula is bounded between [tex]-A[/tex] and [tex]A[/tex]. Hence, the minimum and maximum are -4 and 4, respectively.
Intercepts
The intercepts are set of points of the sinusoidal formula such that [tex]y = 0[/tex]. The sine function is a periodic function which equals 0 each [tex]\pi[/tex] radians.
[tex]4\cdot \sin 2x = 0[/tex]
[tex]\sin 2x = 0[/tex]
[tex]2\cdot x = \sin^{-1} 0[/tex]
[tex]x = \frac{1}{2}\cdot \sin^{-1} 0[/tex]
[tex]x = \frac{1}{2}\cdot [0 \pm \pi \cdot n][/tex], [tex]\forall \,n\in \mathbb{N}_{O}[/tex]

Answer:
they most likely flirting
Answer: If a guy doesn’t give you a direct answer when you ask them out then most likely they are still trying to see if you guys could potentially work out, or it can mean that he is uninterested. BUT don’t give your hopes up, who knows just give him some time and if he doesn’t answer then you know his answer. If he calls you “fugly” then he probably just see’s you as a friend but ngl I’m not even sure because my guy friends always say I’m “beautiful” but never fugly.

The equation of the second line is

Substitute − +x 1 for y in the equation

3 y x = − .
1 1 3

−+= − x x ⇒

3 = x
⇒ 3 = x
Substitute 3 for x in the equation y x =− +1,
to solve for y . So, y =− + =− (3) 1 2 .
The point of intersection is (3, 2) − .
Therefore, p = 3 and q = −2, so
p q⋅ = ×− =− 32 6 .
