Question

please let me know please please please​

Answer 1

HeRe IS UR AnS:

Φ = theta

We have given that,

sinΦ = x and secΦ= y

cotΦ = ?

Solution:

secx = 1/cos x

cos x = 1 / sec x

here,

cosΦ = 1 / sec Φ

= 1/y

now,

cot Φ = 1/ sec

Φ = 1/ y

now,

cot Φ = cos Φ / sinΦ

= (1/y)/ x

= 1/xy
