What is the formula of tan A by 2?
What is the formula of tan A by 2?
tan x/2 = sin x/ (1 + cos x) 1st easy equation tan x/2 = (1 – cos x) /sin x 2nd easy equation.
What is the formula of sin 2A?
How to proof the formula of sin 2A is equals 2 sin A cos A? Note: In the above formula we should note that the angle on the R.H.S. is half of the angle on L.H.S. Therefore, sin 60° = 2 sin 30° cos 30°. The above formula is also known as double angle formulae for sin 2A.
What is the value of sin A by 2?
Again we look at the quadrant; since A is between 90o and 180o, A/2 is between 45o and 90o. That is, it is in the first quadrant – so its sine is positive. So our answer is: sin (A/2) = .
What are equivalent expressions?
Equivalent expressions are expressions that are the same, even though they may look a little different. If you plug in the same variable value into equivalent expressions, they will each give you the same value when you simplify. Learn more about equivalent expression by watching this tutorial!
How do you know if two expressions are equivalent?
Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value(s) for the variable(s).

Are two equations equal?
Two systems of equations are equivalent if they have the same solution(s). Given a system of two equations, we can produce an equivalent system by replacing one equation by the sum of the two equations, or by replacing an equation by a multiple of itself.
What is the fraction equivalent of?
Equivalent fractions are the fractions that have different numerator and denominator but are equal to the same value. For example, 2/4 and 3/6 both are equal to ½. Hence, they are equivalent in nature. These fractions represent the same proportion of the whole.
