Can someone check this, (i do report as needed and i do mark brainliest)? you!

Step-by-step explanation:

cotx/cscx=cosx

Start on the left side.

cos(x)  csc(x)

Apply the reciprocal identity to  csc  (x)  .

cos(x)  1/sin(x)

Simplify  

cos(x)   1/sin(x)cos(x)/sin(x)

Rewrite  cos(x)/sin(x)  as  cot(x)  .

cot(x)

Because the two sides have been shown to be equivalent, the equation is an identity.

cos(x)   csc(x)=cot(x)  is an identity

cot(x)−tan(x)/sin(x)cos(x)=csc^2(x)−sec^2(x)  is an identity

You are correct :)

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
