cos(pi/4 c)=sin(2(pi/4))

cos (\frac{π}{4} c) = sin (2 (\frac{π}{4}))

c = 8 n

Solution steps

cos (\frac{π}{4} c) = sin (2 (\frac{π}{4}))

sin (2 \cdot \frac{π}{4}) = 1

cos (\frac{π}{4} c) = 1

General solutions for

cos (\frac{π}{4} c) = 1

\frac{π}{4} c = 0 + 2 πn

Solve

\frac{π}{4} c = 0 + 2 πn : c = 8 n

c = 8 n

\frac{( 1 - tanh ( 2 x ) )}{( 1 + tanh ( 2 x ) )} = 2

sin (4 θ) = 0.345

- 3 = cot^{2} (x) + 3 csc (x)

4 cos^{2} (θ) + 3 cos (θ) = 1

x, 2 sin^{2} (x) + cos (x) = 1
