Question

Solve the equation sin9theta = sintheta​

Answer 1

Answer:

hii (really its my fault)

Step-by-step explanation:

can we start talk ... m really sorry for hearting u

Answer 2

Step-by-step explanation:

sin9θ = sinθ.

∴9θ = nπ+(−1) nθ (1)

If n be even say 2r then 9θ=2nπ+θ

∴θ=rπ/4

If ne be odd say 2r+1 then 9θ=(2r+1)π−θ

or θ= $\frac{(2r + 1)\pi}{10}$
