We learned about sin theta 0 degrees value along with other degree values here, this far. Also, derived the value for cos degree and tan degrees with respect sin degrees. In the same way, we can find other trigonometric ratios Note: see also table of values of trigonometric functions of other angles.. Sine, cosine, tangent angle 45 degrees (sin 45, cos 45, tg 45) Table values for sine 45, cosine 45, and 45 degree tangent are given below.

It doesn't work like removing the parentheses in algebra. 2. The formula for what sin(A + B) does equal.

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.

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

You might know that cos(60°)=1/2 and sin(60°)=√3/2 as well as tan(45°)=1, but are 30, 45 and 60 the only angles up to 90° with a formula for their trig values? No! There are lots more but not all angles have exact expressions involving nothing more than square-roots.
