-cos(x)+sin(x)=0

- cos (x) + sin (x) = 0

x = \frac{π}{4} + πn

Degrees

x = 4 5^{\circ} + 18 0^{\circ} n

Solution steps

- cos (x) + sin (x) = 0

Rewrite using trig identities

- cos (x) + sin (x) = 0

Divide both sides by

cos (x), cos (x) \neq = 0

\frac{- cos ( x ) + sin ( x )}{cos ( x )} = \frac{0}{cos ( x )}

Simplify

- 1 + \frac{sin ( x )}{cos ( x )} = 0

Use the basic trigonometric identity:

\frac{sin ( x )}{cos ( x )} = tan (x)

- 1 + tan (x) = 0

- 1 + tan (x) = 0

Move

1

to the right side

- 1 + tan (x) = 0

Add

1

to both sides

- 1 + tan (x) + 1 = 0 + 1

Simplify

tan (x) = 1

tan (x) = 1

General solutions for

tan (x) = 1

x = \frac{π}{4} + πn

x = \frac{π}{4} + πn

cos^{4} (2 x) - sin^{4} (2 x) = 1

sin (x) tan (x - 3 0^{\circ}) = 0

- 4 tan^{2} (θ) = - 1

2 cos^{2} (x) + 5 sin (x) + 1 = 0

\frac{125}{sin ( 11 0 ^{\circ} )} = \frac{100}{sin ( b )}
