Trigonometric formulas.

$1). \cos^{2}\theta+\sin^{2}\theta=1$

$2).1-\sin^{2}\theta=\cos^{2}\theta$

$3).1+\tan^{2}\theta=\sec^{2}\theta$

$4).1+\cot^{2}\theta=cosec^{2}\theta$

$5).\sin2\theta=2\sin\theta\cos\theta$

$6).\frac{1-\cos 2x}{2}=\sin^{2}x$

$7).\frac{1+\cos 2x}{2}=\cos^{2}x$

$8).\cos(2x)=\cos^{2}x-\sin^{2}x$

$9).\cos(2x)=2\cos^{2}x-1$

AB Formulas

$10).\cos(A+B)=\cos{A}\cos{B}-\sin{A}\sin{B}$

$11).\cos(A-B)=\cos{A}\cos{B}+\sin{A}\sin{B}$

$8).\sin(A+B)=\sin{A}\cos{B}-\cos{A}\sin{B}$

$8).\sin(A-B)=\sin{A}\cos{B}-\cos{A}\sin{B}$

CD Formulas

$11).\sin{C}-\sin{D}=2\sin\frac{C-D}{2}\cos\frac{C+D}{2}$

$9).\sin{C}+\sin{D}=2\sin\frac{C+D}{2}\cos\frac{C-D}{2}$

$16).\cos{C}-\cos{D}=2\sin\frac{C+D}{2}\sin\frac{D-C}{2}$

$17).\cos{C}+\cos{D}=2\cos\frac{C+D}{2}\cos\frac{C-D}{2}$
