Cosy/1-siny = 1+siny/cosy
varify using trig identity.

See Below.

Step-by-step explanation:

We want to verify the equation:

On the left, we can multiply both layers by (1 + sin(y)):

Multiply:

From the Pythagorean Theorem, we know that sin²(y) + cos²(y) = 1. Hence, 1 - sin²(y) = cos²(y). Substitute:

Cancel:

Hence proven.

i honestly dont know

step-by-step explanation:

the ten thousandths place is the 2. you round it up if, that number in whatever place is 5 or higher.
