WebFree math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor. WebLet us compute the Cosine of 65 degrees using the Taylor series expansion for cos(x) where x is in radians. The value of 65 degrees in radians is: 65 * Π / 180 radians = 1.1344640137963142 radians. We now substitute x = 1.1344640137963142 radians in the cosine series. Let us take a look at the series expansion once again. 1 - x 2 /2! + x 4 /4!

The result can be shown in multiple forms. WebSo the law of cosines tells us that 20-squared is equal to A-squared, so that's 50 squared, plus B-squared, plus 60 squared, minus two times A B. So minus two times 50, times 60, times 60, times the cosine of theta. This works out well for us because they've given us everything. There's really only one unknown. Webcosine = Adjacent / Hypotenuse but if we use secant, it would be 'flipped' (called the reciprocal), becoming Hypotenuse over Adjacent secant = Hypotenuse / Adjacent Example cos (60 degrees) = 0.5 or 1/2 so sec (60 degrees) = 2 or 2/1 ( 17 votes) Show more...
