How do you solve this without using a calculator
My name is Ann [436]

Answer:

A

Explanation:

You must know the basics of Trigonometry to solve this.

First, you must know that

\frac{3\pi}{4}

lies in the second quadrant, so sin is negative.

Next, since

pi/4, is the reference angle of 3 pi/4, this means that we can set up a right triangle with pi/4 as an angle, we get

\cos( \frac{3\pi}{4} )  =  \frac{ \sqrt{2} }{2}

\sin( \frac{\pi}{4} )  =  -  \frac{ \sqrt{2} }{2}

So the answer is A
