-1=cos(pit)

Solution

- 1 = cos (π t)

Solution

t = 1 + 2 n

+1

Solution steps

- 1 = cos (π t)

Switch sides

cos (π t) = - 1

General solutions for

cos (π t) = - 1

π t = π + 2 πn

Solve

π t = π + 2 πn : t = 1 + 2 n

t = 1 + 2 n

Popular Examples

2 tan^{2} (θ) = 6

cos^2(θ+pi/6)= 1/2

cos^{2} (θ + \frac{π}{6}) = \frac{1}{2}

2sin(2x)=2sin(x)

2 sin (2 x) = 2 sin (x)

tan (x) = \frac{1}{7}

cos^{2} (x) = 0.1
