Question

tan theta//cos theta is equal to sin theta×sec square theta
prove​

Answer 1

Step-by-step explanation:

taking c as theta to avoid confusion.

tan c/cos c

now tan c is nothing but sin c/cos c

so, sin c/ cos c *1/cos c

now, cos c is nothing but 1/sec c

so, sin c * sec c * sec c

hence, sin c * sec²c
