Exact Form: The values of trigonometric numbers can be derived through a combination of methods.01) is approximately 0. The value is 1 divided by square root of 2 in fraction form and 0. Let the two legs have length s. What is Sine in Mathematics? Sine, is a trigonometric function of an angle. Each of sine and cosine is a function of an angle, which is usually expressed in terms of radians or degrees.Except where explicitly … For memorising cos 0°, cos 30°, cos 45°, cos 60° and cos 90°. The approximate value of cos 45 is equal to 0. Multiply the numerator of the first fraction by the denominator of the second fraction. The sine, cosine and tangent of the standard Find the Exact Value.pi/2 - math. View Solution.
