Sin 30 value: Sin 30 Formula

Sin 30 Formula : Sin 30 degrees is equal to cos 60 degrees. The value of sin 30 degrees is 1/2. What is the formula for sin 30 ? In an equilateral triangle, the measure of each triangle is 60° and all the sides are equal. Let’s assume all the side to be of 2 cm. Use our sin (x) calculator to find the exact value of sine of 30 degrees - sin ( 30 °) - or the sine of any angle in degrees and in radians. Sine function, which is one of the basic trigonometric functions, relates the angle of a right triangle to the ratio of the length of the opposite side to the hypotenuse. sin 30° = 1/2 = 0.5 The sine of a 30° angle, written as sin 30°, gives the ratio of the length of the side opposite a 30° angle to the hypotenuse in a right-angled triangle . You’ll find this value applied in areas such as triangle solving, unit circle problems, and physics.
