Cos = -1 2

This is the Solution of Question From RD SHARMA book of CLASS 12 CHAPTER INVERSE TRIGONOMETRIC FUNCTIONS This Question is also available in R S AGGARWAL book

A quadratic equation is a second degree The arccosine function is the inverse function of cos(x). arccos(x) = cos-1 (x) For example, If the cosine of 60° is 0.5: cos(60°) = 0.5. Then the arccos of 0.5 is 60°: arccos(0.5) = cos-1 (0.5) = 60° Arccos table Trigonometry (from Greek trigōnon, "triangle" and metron, "measure") is a branch of mathematics that studies relationships between side lengths and angles of triangles. cos(120), cos (240), and all rotations. -1/2 is also equal to -cos(60) & -cos(300). A unit circle will give you a visual.

Statement 3: $$\cos 2x = 2\cos^2 x - 1$$ Proof: It suffices to prove that. $$1 - 2\sin^2 x = 2\cos^2 x - 1$$ Add $$1$$ to both sides of the equation: $$2 - 2\sin^2 x = 2\cos^2 x$$ Now add $$2\sin^2 x$$ to both sides of the equation: $$2 = 2\cos^2 x + 2\sin^2 x = 2(\cos^2 x + \sin^2 x) = 2…

cos(x)=1/2. Take the inverse cosine of both sides of the equation to extract from inside the cosine. The exact value of is .
