WebApr 12, 2024 · These trigonometric identities are the basic formulae that are true for all the values of the reference angle. There are six trigonometric ratios namely sine, cosine, tangent cotangent, secant, and cosecant. The definition of each trigonometric ratio for a reference angle ‘θ’ is mentioned in terms of the sides of a right triangle. WebSolution 1: As we saw above, \cos\theta=0 cosθ = 0 corresponds to points on the unit circle whose x x -coordinate is 0 0. Since these points occur at the points of intersection with the y y -axis, the possible values of \sin \theta sinθ are the possible y y -coordinates, which are 1 1 and -1 −1. _\square . Solution 2:
WebTRIGONOMETRIC FORMULAS Basic Identities The functions cos(θ) and sin(θ) are defined to be the x and y coordinates of the point at an angle of θ on the unit circle. Therefore, sin(−θ) = −sin(θ), cos(−θ) = cos(θ), and sin2(θ) + cos2(θ) = 1. The other trigonometric functions are defined in terms of sine and cosine: WebWe can get the derivatives of the other four trig functions by applying the quotient rule to sine and cosine. For instance, d d x ( tan ( x)) = ( sin ( x) cos ( x)) ′ = cos ( x) ( sin ( x)) ′ − sin ( x) ( cos ( x)) ′ cos 2 ( x) = cos 2 ( x) + sin 2 ( x) cos 2 ( x) = 1 cos 2 ( x) = sec 2 ( x).
