Thread: Trigonometric Functions

I had about 100 questions of stuff due soon and i got stuck on the following, can anyone help

Determine the quadrant of the terminal side of the angle in standard position. Convert degree measures to radians and radian measures to degrees.

1. -45°
2. 7π/10

The point is on the terminal side of an angle in standard position. Give the smallest positive angle measure in both degrees and radians.

3. (-3,-3)

Evaluate the expression exactly without a calculator

4. cos 330°
5. csc 2π/3
6. tan 360°

7. Use a calculator in degree mode to solve cos θ = 3/7 of 0° ≤ θ ≤ 90°.

Use transformations to describe how the graph of the function is related to a basic trigonometric graph. Graph two periods.

8. y = 3+2 cos x
9. y = -2-3 sin (x – π)

State the amplitude, period, phase shift, domain, and range for the sinusoid.

10. g(x) = 3cos4x
11. g(x) = -2cos(3x+1)

Use a calculator to evaluate the expression. Express your answer in both degrees and radians.

12. cos-1 (0.479)
13. tan-1 1

Find the exact value of x without using a calculator.

14. cos x = √3/2, 0 ≤ x ≤ π
15. sec x = 2, π ≤ x ≤ 2π

Please show your workings thus far.

I am new to this forum, but would it be bad for me to solve the questions without the OP showing some work/effort first?

I am still very new to this forum as well.

The best way to 'help' a poster is to see the question and the poster's attempts at solving them. Once we have this a forum member with an expertise in the said area can then point the poster in the right direction with their workings.

Otherwise if questions are just posted and then answered the orignal poster will have no real understanding of the topic.

i agree. it seems as if this poster just wants the answers without even wanting to know how its done..
