These values help in solving different trigonometry problems in maths. Sin 18 Degree by Cos 72 Degree Let’s calculate the value of sin 18 upon cos 72 degrees. sin 18°/cos 72° = [(√5 – 1)/4]/ [(√5 – 1)/4] = 1
Sin Cos formulas are based on the sides of the right-angled triangle. Sin and Cos are basic trigonometric functions along with tan function, in trigonometry. The sine of an angle is equal to the ratio of the opposite side to the hypotenuse whereas the cosine of an angle is equal to the...
The exact value of sin 180 is zero. Sine is known to be one of the primary trigonometric functions which help in determining the angle or sides of a right-angled triangle. It is also called trigonometric ratio. If theta is an angle in a right-angled triangle, then sine theta is equal ...
