What does the Pythagorean theorem look like as an equation?

A
ab = c

B
a^2
2
+ b^2
2
= c^2
2


C
a + b = c

D
a^2
2
b^3
3
=c^2
2

Sin(a)+cos(a)+cot(a)-1=2(csc(x)+1)

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
