Question

show that cos theta (1/1-sin theta - 1/1+sin theta) can be written in the form of k tsn theta and find the value of k.​

Answer 1

Answer:

costheta(1/1-sintheta-1/1+sintheta)

taking lcm inside the bracket

costheta(2sintheta/(1-sin²theta))

costheta(2sintheta/cos²theta)

=2tantheta

hence value of k is 2

Answer 2

Answer:

ostheta(1/1-sintheta-1/1+sintheta)

taking lcm inside the bracket

costheta(2sintheta/(1-sin²theta))

costheta(2sintheta/cos²theta)

=2tantheta

hence value of k is 2

u look soo cute
