simplify (1-cos^2(x))/(1-cos(x))

simplify

\frac{1 - cos ^{2} ( x )}{1 - cos ( x )}

1 + cos (x)

Solution steps

\frac{1 - cos ^{2} ( x )}{1 - cos ( x )}

Factor

1 - cos^{2} (x) : (1 + cos (x)) (1 - cos (x))

= \frac{( 1 + cos ( x ) ) ( 1 - cos ( x ) )}{1 - cos ( x )}

Cancel the common factor:

1 - cos (x)

= 1 + cos (x)

(t + 3)^{2}

\frac{x ^{4} - 1}{x ^{2} + 1}

\frac{( n ^{2} + 7 n + 10 )}{( n + 5 )}

(2^{3}) (2^{7}) (2^{15})

(2 - 53)^{2}
