What is (\sec^2 \theta-1) equal to?(\sec^2 \theta-1) किसके बराबर होता है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (\tan^2 \theta)(\tan^2 \theta)
From (\sec^2 \theta=1+\tan^2 \theta), we get (\sec^2 \theta-1=\tan^2 \theta). Rearrange the formula into a simple form.(\sec^2 \theta=1+\tan^2 \theta) से (\sec^2 \theta-1=\tan^2 \theta) मिलता है। सूत्र को सरल रूप में बदलें।
