False
Step-by-step explanation:
15 isn't divisible by 10
Yes it is true:
(1 - cos^2 x) = sin^2 x Sqr.(1 - cos^2 x) = sin x and (-sinx) True, since sin x negative. Also, x terminates in quadrant 3 and 4. Hope this is helpful
The answer is A)1/2[sin(4x)+sin(2x)]
If you solve for theta, it would be 3pi/4
