Question

Convert the angle to radian measure Enter a fraction in the form "a/b" theta = 120 degrees theta = [x] pi Given the angle below, find a conterminal reference angle such that the angle is positive and between 720 and 1080 degrees. Theta = 2/4 pi Evaluate the trigonometric function (give exact values) Use "a/b" for fractions and for squareroot s Do not rationalize the denominator cos 3 pi/2 = [x] Find the reference angle for the given angle m radians Enter a traction "a/b" theta = -5/4 pi theta = [x] pi Evaluate the trigonometric function (give exact values) Use "a/b" for and "sqr()" for squareroot s. Do not rationalize the denominator sin pi/6 = [x]

Explanation / Answer

Theta=120 degree

To convert it to radian,we have to multiply it by pi/180

120 degree=120*pi/180= 2pi/3

Second question

Here theta=2/4pi=pi/2

Therefore coterminal reference angle=pi/2 + 4pi= 9pi/2=810 degree

third question

cos 3pi/2= cos (pi + pi/2)=cos pi/2=0
