Here, we show you a step-by-step solved example of proving trigonometric identities. This solution was automatically generated by our smart calculator:
cos(x)1−1+sin(x)cos(x)=tan(x)
2
Starting from the left-hand side (LHS) of the identity
cos(x)1+1+sin(x)−cos(x)
3
The least common multiple (LCM) of a sum of algebraic fractions consists of the product of the common factors with the greatest exponent, and the uncommon factors
L.C.M.=cos(x)(1+sin(x))
4
Obtained the least common multiple (LCM), we place it as the denominator of each fraction, and in the numerator of each fraction we add the factors that we need to complete
