Question

what is sin squareroot7/4?

Answer 1

Calculator can do that

Answer 2

i need to find cos

Answer 3

\[\large \sin(\sqrt{\frac{7}{4}}) = \sin (\frac{\sqrt{7}}{2})\] one way you could find cos is by squaring sin, and using the identity sin^2 (x) + cos^2 (x) = 1.

Answer 4

Err...i mean you can take the derivative of sin(sqrt (7)/2)

Answer 5

i can't figure out the answer

Answer 6

sin theta = p/h
cos theta=b/h
=\[\sqrt{45}/\sqrt{7}\]
