Hey guys, just to make sure I am on the right track here on this question: Find the remaining trigonometric functions ofθif cos(θ) = √3/2 andθterminates in QI. Would the sine= 1?

Hey goldbug78.

Recall that sin^2 + cos^2 = 1 and that sin(x) >= 0 as well as cos(x) >= 0 in first quadrant. - January 29th 2013, 06:03 PMSorobanRe: Finding the trig function

Find the remaining trigonometric functions of

if and terminates in quadrant 1.

We are given: .

Hence, is in a right triangle with:

Code:`*`

* *

2 * *

* * x

* θ *

* * * _ * * *

√3

. . . . . . . . . .

Since is in quadrant 1,

You have: .

Go for it!
