cos3X=sinX
Find X, 0 degree < x < 360 degree
Thanks in advance
There's the hard way and the easy way. Personally I like the easy way best:
From the complementary angle formulae: .
Case 1: where n is an integer.
Solve for x and substitute appropriate values of n to get all values of x satisfying the given domain.
Case 2: where n is an integer.
Solve for x and substitute appropriate values of n to get all values of x satisfying the given domain.
