cot theta - tan theta = cos 2 theta / sin theta cos theta Prove the identity. cos (pi - theta) + sin (pi / 2 + theta) = 0 Prove that, sin theta + sin 2 theta + sin 3 theta + ... + sin n theta = dfrac{dfrac{sin n theta}{2} sin dfrac{(n ...
sinx+cosx=0 Solution of a Trigonometric Equation: A trigonometric equation has an infinite number of solutions, and we use an integer n to define its solution. We use the integer to define the solution because all trigonometric functions are periodic so, it repeats its value after a...
therefore, sin 90 degree equals to the fractional value of 1/ 1. sin 90° = 1 the most common trigonometric sine functions are sin 90 degree plus theta \(\begin{array}{l}\sin (90^{\circ}+\theta )=\cos \theta\end{array} \) sin 90 degree minus theta \(\begin{array}{l}\sin...

\(\begin{array}{l}\sin \theta =\frac{opposite ~ side}{hypotenuse ~ side}\end{array} \) sine law: the sine law states that the sides of a triangle are proportional to the sine of the opposite angles. \(\begin{array}{l}\frac{a}{\sin a}=\frac{b}{\sin b}=\frac{c}{\sin ...
Differentiation: Apply the chain rule in the problem below;df(u)dx=dfdu⋅dudx As per the requirement, we have also use the product rule and the product rule. The quotient rule is given by: (fg)′=f′⋅g−g′⋅fg2 The product rule is given as; ...
Therefore, if one angle is 90 degrees we can figure outSin Theta = Cos (90 - Theta)and Cos Theta = Sin (90 - Theta). Should I memorize the unit circle? As stated above, the unit circle ishelpfulbecause it allows us to easily solve for the sine, cosine, or tangent of any degree...
three are considered as primary functions and sine function is one of them. The rest two are tan and cos. We usually define sine theta as the ratio of the opposite side of the right-angled triangle to its hypotenuse. Considering a triangle with ABC as an angle alpha, the sine function ...
sin(90°+θ)=cosθ Sin 90 degree minus theta sin(90°−θ)=cosθ The following are some other trigonometric sine identities: \[sinx=\frac{1}{\textrm{csc x}}\] \[sin^2x+cos^2x=1\] \[sin(-x)=-sinx\] \[sin2x=2sinxcosx\] ...
