sin(x)= 1/(cos(x))

sin (x) = \frac{1}{cos ( x )}

No Solution for x \in R

Solution steps

sin (x) = \frac{1}{cos ( x )}

Subtract

\frac{1}{cos ( x )}

from both sides

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

Simplify

sin (x) - \frac{1}{cos ( x )} : \frac{sin ( x ) cos ( x ) - 1}{cos ( x )}

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

\frac{f ( x )}{g ( x )} = 0 \Rightarrow f (x) = 0

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

Rewrite using trig identities

- 1 + \frac{sin ( 2 x )}{2} = 0

Move

1

to the right side

\frac{sin ( 2 x )}{2} = 1

Multiply both sides by

2

sin (2 x) = 2

- 1 \leq sin (x) \leq 1

No Solution for x \in R

tan (x) + 3 cot (x) = 5 sec (x)

6 sin (θ) + 3 = 0

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

sin (3 θ) = - \frac{1}{2}

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