If tan 3a is equal to sin cos 45 plus sin 30, then the value of a = 0.4.
SQRT(3)/4 - 1/4
Sin -30
sin(40o) = 0.6428
It is:- sin(40) = 0.6427876097
If tan 3a is equal to sin cos 45 plus sin 30, then the value of a = 0.4.
Sin30 degrees is 0.50000
Y=sin X is a function because for each value of X, there is exactly one Y value.
The value of sin A is 5.82 and the actual angle is 19.47 degees
sin(360+30) =sin(30)= 1/2
sin(75) = sin(45 + 30) = sin(45)*cos(30) + cos(45)*sin(30) = [1/sqrt(2)]*[sqrt(3)/2] + [1/sqrt(2)]*[1/2] = 1/[2*sqrt(2)]*[sqrt(3) + 1] that is [sqrt(3) + 1] / [2*sqrt(2)]
SQRT(3)/4 - 1/4
Sin(30) + cosec(30) = sin(30) + 1/sin(30) = 0.5 + 1/0.5 = 0.5 + 2 = 2.5
The exact value of sin 22.5 is 0.382683432
mostly it comes from memorization. If sin 30 = 1/2, then arcsin (1/2) = 30
Sin theta of 30 degrees is1/2
what is the value of sin 75 degree
