Values of the other trigonometrical ratios of the standard angles. Standard angles from the trigonometrical ratios table therefore we can easily find the Trigonometric Formula Sheet De nition of the Trig Functions Right Triangle De nition Assume that:0< < or 0 < <90 2 hypotenuseopposite adjacent opp sin hypadj cos hypopp tan adj hyp csc opphyp sec adjadj cot opp Unit Circle De nition Assume can be any angle. Since, we know the sin and cos value of the Respectively the positive square roots of 4/4, 3/4, 2/4, 1/4, 0/4 All the fundamental trigonometric identities are derived from the six trigonometric ratios. All these trigonometric ratios are defined using the sides of the right triangle, such as an adjacent side, opposite side, and hypotenuse side.

Similarly cosine of the above standard angels are They are sine, cosine, tangent, cosecant, secant, and cotangent. The standard angles 0°, 30°, 45°, 60° and 90° are respectively the If θ be an acute angle, the values of sin θ and cos θ lies between 0 and 1 (both inclusive). (d) write the values of sin 0°, sin 30°, sin 45°, sin 60° and sin 90° in reverse order and get the values of cos 0°, cos 30°, cos 45°, cos 60° and cos 90° respectively. Identities expressing trig functions in terms of their complements. With these types of functions, we use algebraic techniques like factoring, the quadratic formula, and trigonometric identities to break the equation down to equations that are easier to work with. This is probably the most important trig identity. This creates an equation that is a polynomial trig function. (c) these numbers given the values of sin 0°, sin 30°, sin 45°, sin 60° and sin 90° respectively. The Pythagorean formula for sines and cosines. (a) divide the numbers 0, 1, 2, 3 and 4 by 4, Get to know some special rules for angles and various other. Note: Values of sin θ and cos θ lies between 0 and 1 (both inclusive) Trig Cheat Sheet: Trigonometry is the study of triangles, which contain angles, of course.
