(3tan^2(x)-5)/(cos(x)+1)=0

\frac{3 tan ^{2} ( x ) - 5}{cos ( x ) + 1} = 0

x = 0.91173 \dots + πn, x = - 0.91173 \dots + πn

Solution steps

\frac{3 tan ^{2} ( x ) - 5}{cos ( x ) + 1} = 0

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

3 tan^{2} (x) - 5 = 0

Solve by substitution

tan (x) = \frac{5}{3}, tan (x) = - \frac{5}{3}

tan (x) = \frac{5}{3} : x = arctan (\frac{5}{3}) + πn

tan (x) = - \frac{5}{3} : x = arctan (- \frac{5}{3}) + πn

Combine all the solutions

x = arctan (\frac{5}{3}) + πn, x = arctan (- \frac{5}{3}) + πn

Show solutions in decimal form

x = 0.91173 \dots + πn, x = - 0.91173 \dots + πn

sin (3 x) = \frac{1}{2}, 0 \leq x \leq 2 π

cos (θ) = sec (θ), 0 \leq θ < 2 π

\frac{441}{841} + sin^{2} (t) = 1

3 cot (\frac{2 x}{3}) - 1 = 0

2 sin (3 x) = 1, 0 \leq x \leq 4 π
