Trigonometry - verify identity:

cos (x - y) / sin (x + y) = 1 + cotxcoty / cotx + coty

The required verification is given below.

Step-by-step explanation:

To verify:

Consider,

Left hand side =

Now by using Trigonometric identities,

Now we get,

Left hand side =

Now dividing Numerator and Denominator by we get

Left hand side =

Now we have identity

and then

Left hand side =

Which is equal to our Right hand side required identity

This is the way we have

Left hand side = Right hand side   Proved.

answer: i can’t tell you that

step-by-step explanation:

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
