How to solve for exact values trigonometry

WebThe Pythagorean Identities are based on the properties of a right triangle. cos2θ + sin2θ = 1. 1 + cot2θ = csc2θ. 1 + tan2θ = sec2θ. The even-odd identities relate the value of a trigonometric function at a given angle to the value of the function at the opposite angle. tan(− θ) = − tanθ. cot(− θ) = − cotθ. WebUse the trigonometric ratios to calculate accurate values for the angles 30° and 60°. A square with side lengths of 1 cm can be used to calculate accurate values for the …

Webwe see 'x' and 'c' to be squared i.e. 2*x^2 = c^2 If you recall studying 'Real Numbers' or 'Indices', you would know that the root of 'x^2' is 'x' , the root of 'c^2' is 'c' and of '2' is ' (root sign)2'. So by simply finding root of both side: 2*x^2 = c^2, will be (root)2*x = c and so we write it as : x* (root)2 = c,
