sin(A+B) ≡ sin(A)cos(B) + sin(B)cos(A) ⇒ sin(75°) = sin(30+45)° = sin(30°)cos( 45°) + sin(45°)cos(30°) = ½ × 1/√2 + 1/√2 ×(√3)/2 = 1/(2√2) + (√3)/(2√2)

We will begin calculating the Sin values for different degrees such as Sin 0°, Sin 30°, Sin 45°, Sin 60°, and Sin 90°. Sin 0° = √0/4 = O. Sin 30° ==√1/4= ½. Sin 45° =√2/4= ½. Sin 60° = √3/4 = √3/2. Sin 90° = √4/4 = 1.

sin 45°: You may recall that an isosceles right triangle with sides of 1 and with hypotenuse of square root of 2 will give you the sine of 45 degrees as half the square root of 2. There is a trick to remember the values of sine of angles 0,30,45,60 and 90. Write 0,1,2,3,4 below the above mentioned angle values , Divide each one by 4 0/4, 1/4, 2/4, 3/4, 4/4, Obtain square root of each of the above fractions, 0, 1/2 , 1/sqrt( First of all you need to assure that whether X(angle) is in degree or radian. After that you can find your result,Consider a right triangle with angle X= 45°,then it is obvious that third will also be 45°.hence the side length of trinagle are L, L Now let us discuss different values For sin For memorising sin 0°, sin 30°, sin 45°, sin 60° and sin 90° We should learn it like sin 0° = 0 sin 30° = 1/2 sin 45° = 1/√2 sin 60° = √3/2 sin 90° = 1 So, our pattern will be like 0, 1/2, 1/√2, √3/2, 1 As it is, there's only a few angles for which the sine and cosine functions have exact values - 30, 45, and 60 degrees are the useful ones, and it's also possible (once knowing these) to find others such as 15 degrees.
