Question

prove sin^A + 1/tan^2A = 1​

Answer 1

Answer:

So can't proved

Step-by-step explanation:

$\frac{ sin^{2}A + 1}{tan^{2}A}\\\\ => \frac{sin^{2}A + 1}{\frac{sin^{2}A}{cos^{2}A} }\\\\ =>\frac{cos^{2}A*sin^{2}A+cos^{2}A}{sin^{2}A} \\\\=>cos^{2}A+cot^{2}A\\\\=>cosec^{2}A+cot^{2}A$

If there is ' - ' symbol between this value is ' 1 ' .
