(sin(t)-1)cos(t)=0

(sin (t) - 1) cos (t) = 0

t = \frac{π}{2} + 2 πn, t = \frac{3 π}{2} + 2 πn

Degrees

t = 9 0^{\circ} + 36 0^{\circ} n, t = 27 0^{\circ} + 36 0^{\circ} n

Solution steps

(sin (t) - 1) cos (t) = 0

Solving each part separately

sin (t) - 1 = 0 or cos (t) = 0

sin (t) - 1 = 0 : t = \frac{π}{2} + 2 πn

sin (t) - 1 = 0

Move

1

to the right side

sin (t) - 1 = 0

Add

1

to both sides

sin (t) - 1 + 1 = 0 + 1

Simplify

sin (t) = 1

sin (t) = 1

t = \frac{π}{2} + 2 πn, t = \frac{3 π}{2} + 2 πn

t = \frac{π}{2} + 2 πn, t = \frac{3 π}{2} + 2 πn

Combine all the solutions

t = \frac{π}{2} + 2 πn, t = \frac{3 π}{2} + 2 πn

csc (x) = 1, 0 \leq x \leq 2 π

4 sin (θ) + 33 = 3

cos (2 x) - 2 sin (x) = 0

sin (x) - 4 cos (x) = 0

2 sin (x) + 53 = 63
