Solution for 0=-40sin(2t)-60cos(2t) equation:


Simplifying
0 = -40sin(2t) + -60cos(2t)

Remove parenthesis around (2t)
0 = -40ins * 2t + -60cos(2t)

Reorder the terms for easier multiplication:
0 = -40 * 2ins * t + -60cos(2t)

Multiply -40 * 2
0 = -80ins * t + -60cos(2t)

Multiply ins * t
0 = -80inst + -60cos(2t)

Remove parenthesis around (2t)
0 = -80inst + -60cos * 2t

Reorder the terms for easier multiplication:
0 = -80inst + -60 * 2cos * t

Multiply -60 * 2
0 = -80inst + -120cos * t

Multiply cos * t
0 = -80inst + -120cost

Reorder the terms:
0 = -120cost + -80inst

Solving
0 = -120cost + -80inst

Solving for variable 'c'.

Move all terms containing c to the left, all other terms to the right.

Add '120cost' to each side of the equation.
0 + 120cost = -120cost + 120cost + -80inst
Remove the zero:
120cost = -120cost + 120cost + -80inst

Combine like terms: -120cost + 120cost = 0
120cost = 0 + -80inst
120cost = -80inst

Divide each side by '120ost'.
c = -0.6666666667ino-1

Simplifying
c = -0.6666666667ino-1
