Check Q11 here. http://8mundo.forumchitchat.com/file?id=1660235
PART 1-
sin (a+b) =sinacosb+cosasinb
*so for sin (3x) = = sin(2x + x)
= sin(2x)cos(x) + cos(2x)sin(x)
=cosx [sin(2x)cos(x) + cos(2x)sin(x)]
= 2sin(x)cos(x)cos(x) + (1 - 2sin² (x) ) sin(x)
= 2sin(x)cos² (x) + sin(x) - 2sin³ (x)
= 2sin(x) ( 1 -sin² (x) ) + sin(x) - 2sin³ (x)
= 2sin(x) -2sin³ (x) + sin(x) - 2sin³ (x)
= -4sin³ (x) + 3sin(x)
= 3sin(x) - 4sin³ (x)
Hi,
I'm doing trigonometry P1 and I'm stuck at Exercise 10B : Use the symmetric and periodic properties of the sine, cosine and tangent functions to establish the following results:
(a.) sin(90-theta) = cos theta
(b.) sin(270+theta) = -cos theta
(c.) sin(90+theta) = cos theta
(d.) cos(90+theta) = -sin theta
(e.) tan(theta - 180) = tan theta
How do I solve these? Please help.

Remember if the digits are odd, remove sin and and cos and vice versa, in case of tan, remove tan and add cot and vice versa.
Remember ASTC graph.
(a) sin(90 - theta) = 90 is odd so add cos remove sin. 90 - thetha = A so cos theta.
(b) sin (270+ theta) = 270 is odd so remove sin add cos, 270 + theta = C so sin is -ve = - cos theta.
(e) tan(-(180-theta)) = 180 is even, so no changes. tan(-theta) = tan theta.
REST TRY OUT YOURSELF, if u still have doubts, we are here to solve them.
