No Angle Needed: tan θ + cot θ = 4

CBSE Class 10 · Solve it one decision at a time. A wrong pick earns a nudge, never the answer.

Step 1 of 4

The problem

If tan⁡θ+cot⁡θ=4\tan\theta + \cot\theta = 4, find the value of sec⁡2θ+cosec⁡2θ\sec^2\theta + \operatorname{cosec}^2\theta.

Step 1 · Your move

Before the guided steps, what value did you get for sec⁡2θ+cosec⁡2θ\sec^2\theta + \operatorname{cosec}^2\theta?

tan⁡θ+cot⁡θ=4\tan\theta + \cot\theta = 4
