The maximum number of turning points in a cubic function is 2.
In this case,
The discriminant is
, which means the derivative has no real roots. This means there are no critical points and thus no turning points/relative extrema.
In this case,
The discriminant is
Answer:
sinΘ =
Step-by-step explanation:
using the identity
sin²x + cos²x = 1 ( subtract cos²x from both sides )
sin²x = 1 - cos²x ( take square root of both sides )
sinx = ±
given
cosΘ = - , then
sinΘ = ±
= ±
= ±
= ±
since Θ is in quadrant II where sinΘ > 0 , then
sinΘ =
