Question

The value of tan² teta × (cosec² teta-1)=​

Answer 1

Answer:

= 1

Step-by-step explanation:

=tan^2¢ * (cosec^2¢ -1)

=sin^2¢/cos^2¢{(1/sin^2¢)-1}

......(cosec=1/sin)

=sin^2¢/cos^2¢{(1-sin^2^)/sin^2¢}

=sin^2¢/cos^2¢(cos^2¢/sin^2¢)

.. (sin^2¢+cos^2¢=1)

= 1

Answer 2

Answer:

${tan}^{2} \times \frac{1}{ { \cosec}^{2} } = {tan}^{2} \times {sin}^{2}$
