Question 1108328: Cos3xsin2x=0
Answer by rothauserc(4718)   (Show Source):
You can put this solution on YOUR website! cos(3x) * sin(2x) = 0
:
there are two equations to solve
:
1) cos(3x) = 0
:
2) sin(2x) = 0
:
using equation 1, take the inverse cosine of both sides of =
:
3x = pi*m + (pi/2) for m an element of Z
:
x = (pi*m/3) + (pi/6) for m an element of Z
:
using equation 2, take the inverse sin of both sides of =
:
2x = pi * m for m an element of Z
:
x = (pi * m/2) for m an element of Z
:
************************************************
x = (pi*m/3) + (pi/6) for m an element of Z or
:
x = (pi * m/2) for m an element of Z
