1-cos(2x)=0

Solution

1 - cos (2 x) = 0

Solution

x = πn

+1

Solution steps

1 - cos (2 x) = 0

Move

1

to the right side

- cos (2 x) = - 1

Divide both sides by

- 1

cos (2 x) = 1

General solutions for

cos (2 x) = 1

2 x = 0 + 2 πn

Solve

2 x = 0 + 2 πn : x = πn

x = πn

1 = 4 tan (- \frac{4}{81} + c)

15cos^2(x)+7cos(x)-2=0

15 cos^{2} (x) + 7 cos (x) - 2 = 0

2(sin(t))^2-sin(t)-1=0

2 (sin (t))^{2} - sin (t) - 1 = 0
