Answer 1

Answer:

$\underline{\boxed{\red{Formulas\:\:of\:\:trigonometry:-}}}$

1.Sum And Difference Of Angles:

$1.Sin A \:\:Sin B = \frac{1}{2} [cos(A-B)-cos(A+B)]$

$2.cos A \:\:cos B = \frac{1}{2} [cos(A-B)+ cos(A+B)]$

$3.Sin A \:\:cos B = \frac{1}{2} [sin(A+B)+ sin(A-B)]$

$4.cos A \:\:sin B = \frac{1}{2} [cos(A+B)+ sin(A-B)]$

2.Double Angle Formulas:

$1.sin2\theta= 2sin\theta \:cos\theta$

$2.cos2\theta= Cos^2\theta - Sin^2\theta$

           $= 2cos^2\theta-1$

           $= 1-2sin^2\theta$

$3.tan2\theta = \bold{\frac{2Tan\theta}{1-Tan^2\theta}}$

3.Triple Angle Formula:

$1.sin3\theta= 3Sin\theta - 4Sin^3 \theta$

$2.cos3\theta=4cos^3\theta - 3cos\theta$

$3.tan3\theta= (3tan\theta-tan^3 \theta) / (1-3tan^2 \theta)$

$4.cot3\theta =\bold{ \frac{cot^3\theta - cot\theta}{3cot^2\theta - 1}}$
