Cosine Calculator


The Cosine Calculator solves the unsolvable math problem every high school student has but their parents won't help them with.


Since cos(α) = b/c, from this definition it follows that the cosine of any angle is always less than or equal to one, and it can take negative values. The cosine of a 90-degree angle is equal to zero, since in order to calculate it we would need a triangle with two 90-degree angles, which is the definition of a straight line. As the third side of the triangle does not exist (length is 0), the cosine equals zero (0 divided by the length of the hypotenuse equals 0). You can use this cosine calculator to verify this. To find the trigonometric functions of an angle, enter the chosen angle in degrees or radians. Underneath the calculator, six most popular trig functions will appear - three basic ones: sine, cosine and tangent, and their reciprocals: cosecant, secant and cotangent. Additionally, if the angle is acute, the right triangle will be displayed, which can help you in understanding how the functions may be interpreted.

If you want to Calculating the cosine of an angle with the calculator scientific, the first thing to check is whether it is set in degrees or radians. This is vital since 60 degrees is not the same as 60 radians. If you would like more information, in our degrees to radians we explain in more detail the differences between the two ways of expressing angles. The operation of this online cosine calculator is very easy. Simply enter the value of the angle and select the type of units (degrees or radians). Then press the calculate button and you will automatically know the cosine of the angle you have entered. Remember that the cosine of an angle can only take values between -1 and 1.
