Trigonometric identities were used to simplify expressions of trigonometric functions. Pascal's triangle is a triangular arrangement of binomial coefficients. Could it be possible to marry this two?Christopher WhiteChristopher Schwaner

The above identities are often called double-angle formulas. Formulas that express the powers of the sine and cosine of an argument in terms of the sine and cosine of multiples of the argument are frequently useful. Examples are The formulas for cos2 ɸ and sin2 ɸ may be used to find...
We are writing and illustrating a story about the Black and Latiné communities, and the intersectionality between those identities and others. We are writing something for everyone. No matter what part of your life, whether you are a comic reader or not, there is something for everyone to enj...
Hint:Here the given question is about the relationship between sine and cosine. Before starting this question, we need to know about what is the definition of sine and cosine. After that by illustrating some triangles we can find out the relationship between sine and cosine. ...

What is the sine, cosine and tangent of 270 degrees?. Ans: Hint: Express ${{270}^{\\circ }}\\text{ into }\\left( {{270}^{\\circ }}+\\theta \\right)$ . Then we should use the following two identities for sin and cosine respectively, $\\sin \\left( {{...
By trigonometric identities, we know; sin2θ+ cos2θ = 1 Therefore, c2= a2+ b2– 2ab cos C Hence, proved. Cosine Formula The formula to find the sides of the triangle using cosine rule is given below: b=a2+c2–2accosy Sine Formula ...
From the definition of the sine of angleA,sinA=length of side opposite to angleAlength of hypotenuse,and thePythagorean theorem, one has the useful identitysin2A+ cos2A= 1.Other useful identities involving the cosine are the half-angle formula,cos (A2) =1 + cosA2;and the double-angle fo...
