Nov 14, 2011 . sin 15° = sin(45-30) = sin45cos30 - cos45sin30 = (1/√2)(√3/2) - (1/√2)(1/2) = (√3 - 1)/(2√2) so cos 15° the same way and for the 2008-06-02 The cos of 37 degrees is 0.79864, the same as cos of 37 degrees in radians. To obtain 37 degrees in radian multiply 37° by / 180° = 37/180 . Cos 37degrees = cos (37/180 × .

We know that cos (a-b) = cos a * cos b + sin a *sin b cos 15 = cos (45–30) => cos 15 = cos 45 * cos 30 + sin 45 * sin 30 => cos 15 = (1/√2)* (√3/2) + (1/√2 The value of cos 60 takes place in the first quadrant. Some degree values of sine functions and cosine functions are taken from the trigonometry t able to find the value of cos 60 degrees. We know that. 90° – 30° = 60° ———– (1) From the trigonometry formula, sin (90° – a) = cos a. We can find the value of cos 60. We can write it as Click here👆to get an answer to your question ️ Find the value of x (in deg.) , if sin2x = sin 60^∘cos 30^∘ - cos 60^∘sin 30^∘ Teorija tēmā Sin, cos, tg vērtības.
