Example on Sin Cos Formula Example: Find the value of sin 20° sin 40° sin 60° sin 80°. Solution: Given: sin 20° sin 40° sin 60° sin 80° This can be written as: ⇒ sin 60° sin 20° sin 40° sin 80° Substitute sin 60° = √3/2 ...
π/6. q4 what is the formula for sine function? sine of an angle, in a right-angled triangle, is equal to the ratio of opposite side of the angle and hypotenuse. sine a = opposite side/hypotenuse q5 what is the value of cos 30 and tan 30? the value of cos 30 degrees is √3/...
2.What is the formula of sin? The formula of the sine of an acute angle is defined as the ratio of the length of the side directly opposite the angle to the length of the longest side (hypotenuse) of the triangle Sin \Theta = \frac{p}{h} 3.Is sine function even or odd? The s...

Sine Function Formula The diagram given below shows that Sin α = BC/AB. Hence, we can write the formula as: Sin α = a(opposite)/h(hypotenuse) The side opposite to the right angle is the longest side of the triangle which is known as the hypotenuse(H). The side that is opposite ...
