Solved example of proving trigonometric identities, Combine fractions with different denominator using the formula: $\displaystyle\frac{a}{b}+\frac{c}{d}=\frac{a\cdot d + b\cdot c}{b\cdot d}$, When multiplying two powers that have the same base ($\cos\left(x\right)$), you can add the exponents, Apply the trigonometric identity: $1-\cos\left(x\right)^2$$=\sin\left(x\right)^2$, Multiplying polynomials $\cos\left(x\right)$ and $1+\sin\left(x\right)$, Factor the polynomial $\cos\left(x\right)+\cos\left(x\right)\sin\left(x\right)$ by it's GCF: $\cos\left(x\right)$, Simplify the fraction $\frac{\sin\left(x\right)\left(\sin\left(x\right)+1\right)}{\cos\left(x\right)\left(1+\sin\left(x\right)\right)}$ by $\sin\left(x\right)+1$, Apply the trigonometric identity: $\frac{\sin\left(x\right)}{\cos\left(x\right)}$$=\tan\left(x\right)$, Since both sides of the equality are equal, we have proven the identity. Download free on iTunes. Trig identities are very similar to this concept. sin = tan/ sec = 1/ cosec if you put it simply it implies that sin equals divided cosec. prove csc ( θ) + cot ( θ) tan ( θ) + sin ( θ) = cot ( θ) csc ( θ) $prove\:\cot\left (x\right)+\tan\left (x\right)=\sec\left (x\right)\csc\left (x\right)$. prove csc ( θ) + cot ( θ) tan ( θ) + sin ( θ) = cot ( θ) csc ( θ) $prove\:\cot\left (x\right)+\tan\left (x\right)=\sec\left (x\right)\csc\left (x\right)$.
