Cos Double Angle Formula Tan Double Angle Formula Lesson Summary Frequently Asked Questions What is the double angle formula for cos? The cosine double angle formula states that for an angle 'x', cos 2x = cos^(2) x - sin^(2) x. The double angle formula is used to calculate sin 2x...
Step 1 –In the first step, we need to enter the angle for the double of which we need to find the values of sin , cos and tan . For instance, if we wish to find the value of sin 120o, we need to enter 60 as the input value. Below is the snapshot of how the value will...

This result is called thesine of a double angle.It is useful for simplifying expressions later. Cosine of a Double Angle Using a similar process, we obtain thecosine of a double angleformula: cos 2α= cos2α− sin2α Proof This time we start with thecosine of the sum of two angles...
Returns the trigonometric cosine of an angle. Special cases: If the argument is NaN or an infinity, then the result is NaN. If the argument is zero, then the result is1.0. Java documentation forjava.lang.StrictMath.cos(double). Portions of this page ...
