Prove the identity

sin squared 0 with line/2 = csc zero with line -cot zero with a line /2csc zero with a line

To prove the identity, let's simplify each side of the equation separately and then compare them.

Starting with the left-hand side (LHS):
sin^2(0°/2)

We know that sin(0°) = 0. Using this information, we can rewrite sin^2(0°/2) as sin^2(0°)/4.

Since sin^2(0°) = 0, we have:
LHS = 0/4 = 0

Now, let's simplify the right-hand side (RHS):
csc(0°) - cot(0°/2) * csc(0°)

We know that csc(0°) is undefined because it is equal to 1/sin(0°), and sin(0°) is 0.

Also, cot(0°/2) can be simplified as cot(0°) since dividing any number by 2 does not change its value. Cot(0°) = cos(0°)/sin(0°). However, sin(0°) is still 0, so cot(0°) is undefined.

Now, let's see RHS:
RHS = undefined - undefined * undefined

Since both terms on the RHS are undefined, the whole RHS is undefined.

Now, comparing the LHS and RHS we get:
0 = undefined

Since 0 is not equal to undefined, the identity is not valid.

Therefore, the identity sin^2(0°/2) = csc(0°) - cot(0°/2) * csc(0°) is not true.
