The equivalent expression of the<u> different of two square</u> is -1
Given the following expressions
a cot α = 1
a = 1/cot α = sinα/cosα
b = 1/cos α
We are to find the expression a² - b²
According to <u>difference of two squares;</u>
a² - b² = (a + b) (a - b)
Substitute the given expressions into the formula as shown:

This shows that the equivalent expression of the<u> difference of two squares</u> is -1
