WebFirst, draw the vectors on any piece of paper. One way to approach this problem is to draw one vector that has an angle of elevation of 0 degrees, which just means that's parallel to the x-axis, and draw the other vector with an angle of elevation of 60 degrees. WebCos (A + B) = Cos A cos B – Sin A sin B. Let’s equate B to A, i.e A = B. And then, the first of these formulae becomes: Cos (t + t) = Cos t cos t – Sin t sin t. so that Cos 2t = Cos2t – Sin2t. And this is how we get second double-angle formula, which is so called because you are doubling the angle (as in 2A).

WebInverse cosine (\cos^ {-1}) (cos−1) does the opposite of the cosine. Inverse tangent (\tan^ {-1}) (tan−1) does the opposite of the tangent. In general, if you know the trig ratio but not the angle, you can use the corresponding inverse trig function to find the angle. This is expressed mathematically in the statements below.
