1+sinx +cosx

1-sinx=2Secx (2)1+Cosx

1-Cosx=Cosecx+Cotx (3)tanx

Secx-1+tanx

Secx+1=2Cosecx (4)tanx

1-cotx+Cotx

1-tanx=1+Secx.Cosecx (5)1

1-Sinx-1

1+Sinx=2Secx.tanx (6)Cosx

1+Sinx+1+Sinx

Cosx=2Secx (7)1+tan2x

1+Cot2 (1-tanx

1-Cotx)2 (8)1+Sinx

Cosx+Cosx

1+Sinx=2Secx (9)1+2tan2x

Cos2x=tan4x+Sec4x (10)(1-Sinx-Cosx)2=2(1-Sinx)(1-Cox)$$\begin{array}{c}\frac{cosx}{1+sinx}+\frac{cosx}{1-sinx}=2Secx\\ \\ \sqrt{\frac{1+Cosx}{1-Cosx}}=Cosecx+Cotx\\ \\ \frac{tanx}{Secx-1}+\frac{tanx}{Secx+1}=2Cosecx\\ \\ \frac{tanx}{1-cotx}+\frac{Cotx}{1-tanx}=1+Secx.Cosecx\\ \\ \frac{1}{1-Sinx}-\frac{1}{1+Sinx}=2Secx.tanx\\ \\ \frac{Cosx}{1+Sinx}+\frac{1+Sinx}{Cosx}=2Secx\\ \\ \frac{1+ta{n}^{2}x}{1+Co{t}^2}(\frac{1-ta{n}^{}x}{1-Cotx}{)}^2\\ \\ \frac{1+Sinx}{Cosx}+\frac{Cosx}{1+Sinx}=2Secx\\ \\ 1+\frac{2ta{n}^2{x}^{}}{Co{s}^{2}x}=ta{n}^{4}x+Se{c}^{4}x\\ \\ (1-Sinx-Cosx{)}^2=\sqrt{2(1-Sinx)(1-Cox)}\end{array}$$ For more Question of Mathematics and other Subject Please Visit https://www.electricaldiary.com
