First let us work through an example. Get the answer to Integral of sin(x)^4/cos(x)^3 with the Cymath math problem solver - a free math equation solver and math solving app for calculus and algebra. Cos (alpha-3theta)÷cos 3 theta=sin (alpha- 3theta)÷sin 3 theta = m then what is cos2alpha? 1 Answer(s) Available Find out the maximum value of x for given this inverse trigonometric function. First look at the graph of y = sin(4x): Since the displacement is - ½, we can correctly assume that if we shift the above graph to the left by a distance of ½, we will get the graph y = sin(4x + 2). cos 1+sin + 1+sin cos = 2sec 5. INTEGRAL sin^n(x)*dx. Since sine and cosine take values between 1 and 1, the values of the product sin(2x+ 7)cos(x2) will be between 1 and 1. The solutions can be seen if we draw the graphs of f(x) = sin x and g(x) = cos x. Evaluate the following integral.
