Solving Trigonometric Equations by Using Identities Solve the given equation.

5. tan2θ − 2 sec θ = 2

To determine

To solve: The trigonometric equation tan2θ2secθ=2 by using identities.

Explanation of Solution

Calculation:

Simplify the given equation tan2θ2secθ=2 as follows,

tan2θ2secθ=2(sec2θ1)2secθ2=0sec2θ2secθ3=0(secθ+1)(secθ3)=0

Now find the values of θ for the factor (secθ+1) as follows,

secθ+1=0secθ=11cosθ=1cosθ=1θ=π

Similarly, the value of θ for the factor (secθ−<
