- cos (x) = - 1

Solution

x = 2 πn

+1

Solution steps

- cos (x) = - 1

Divide both sides by

- 1

cos (x) = 1

General solutions for

cos (x) = 1

x = 0 + 2 πn

Solve

x = 0 + 2 πn : x = 2 πn

x = 2 πn

sin^{2} (x) csc (x) = - \frac{1}{2}

sec^{2} (2 x) - 1 = 0

1 = 2 cos (x)

solvefor x,y=arcsin(x/(11))solve for

x, y = arcsin (\frac{x}{11})

(sin(48))/(13)=(sin(b))/(16)

\frac{sin ( 4 8 ^{\circ} )}{13} = \frac{sin ( b )}{16}
