WebLearn how to solve differential calculus problems step by step online. Find the derivative of 3/5x-4/7. The derivative of a sum of two or more functions is the sum of the derivatives of each function. The derivative of the constant function (-\\frac{4}{7}) is equal to zero. The derivative of the linear function times a constant, is equal to the constant. WebThe first question is because y 2 = y ⋅ y, by definition. The final answer is not correct. To make it correct, we can use the identity. sinh 2 y = 2 sinh y cosh y. Then we'll have. ( 12 cosh ( 4 x)) cosh ( 4 x) sinh ( 4 x) = 12 cosh 4 x ( 1 2 sinh 8 x) = 6 cosh 4 x sinh 8 x. Share. Cite.

WebThe derivatives of the cosine functions, however, differ in sign: (d/dx)cosx = −sinx, but (d/dx)coshx = sinhx. As we continue our examination of the hyperbolic functions, we … WebQ: Q2 find the derivative of the following: 1) y = 2stn (5x) 2) y = Inxn cosh 5x ,3) xsin14y = y tan-4x. A: As per our guidelines we are supposed to answer only first three parts. Kindly repost other parts as… Weby =cosh−1 x. By definition of an inverse function, we want a function that satisfies the condition x =coshy = e y+e− 2 by definition of coshy = e y+e−y 2 e ey = e2y +1 2ey. 2eyx = e2y +1. e2y −2xey +1 = 0. (ey)2 −2x(ey)+1 = 0. ey = 2x+ √ 4x2 −4 2 = x+ x2 −1. ln(ey)=ln(x+ x2 −1). y =ln(x+ x2 −1). Thus cosh−1 x =ln(x+ x2 ... citing zarathustra
