$$=2x\sec^{2}x\tan x+2\sec^{2}x$$ What you did was increase the power rather than decreasing it. In general, the derivative of secant raised to a power is If we recognize that sin 2 (x) + cos 2 (x) = 1, and that 1/cos 2 (x) is sec 2 (x) $$= \frac{1}{cos^2(x)} = sec^2(x)$$ The result is: $$\frac{d}{dx} tan(x) = sec^2(x)$$ Use the graph below to understand why sec 2 (x) gives the slope of tan(x) at any point between ±π/2 (remember that the tangent function is infinite at multiples of ±π/2 Apr 16, 2009 · Consider the following function: x^x Find (d/dx)x^x You cannot use either of the rules (d/dx)x^n = nx^(n-1) or (d/dx)e^x = e^x. In the first rule the exponent is a CONSTANT, in the second the base is a CONSTANT (in particular it is e.) We can solve this problem using the chain rule. For more information on the specifics of the chain rule, see here: What is chain rule of differentiation? We know that $\dfrac{1}{\cos 2x} = (\cos 2x)^{-1}$. Rules of Derivatives: There are several rules of derivatives which can be used to differentiate expressions. Some of those rules are chain rule, power rule and some trigonometric formulas.

The limit for this derivative may not exist. If there is a limit, then f (x) will be differentiable at x = a. The function of f'(a) will be the slope of the tangent line at x=a. To provide another example, if f(x) = x 3, then f'(x) = lim(h→0) (h+x) 3 - x 3 / h = 3x 2 and then we can compute f''(x) : f''(x) = lim(h→0) 3(x+h) 2 - 3x 2 / h

The parser is implemented in JavaScript, based on the Shunting-yard algorithm, and can run directly in the browser. y = tan(x2) = tan(u) ∴ dy du = sec2(u) = sec2(x2) u = x2, ∴ du dx = 2x Use the chain rule What is the derivative of #tan^2 x#? Calculus Differentiating Trigonometric Functions Derivative Rules for y=cos(x) and y=tan(x) 1 Answer Jim G. d/dx (2^x) = 2^x * ln2 In order to be able to calculate the derivative of 2^x, you're going to need to use two things the fact that d/dx(e^x) = e^x the chain rule The idea here is that you can use the fact that you know what the derivative of e^x is to try and determine what the derivative of another constant raised to the power of x, in this case equal to 2, is.

In calculus, trigonometric substitution is a technique for evaluating integrals. Moreover, one may use the trigonometric identities to simplify certain integrals containing radical expressions.[1][2] Like other methods of I n = tan n−2 x tan 2 x dx と見る． ここで dx の形を作れば，被積分関数が f n (x)f’(x) の形になり，置換積分により簡単に計算できることに目を付ける． 数学Iで習う三角比の相互関係の公式 sin 2 x+ cos 2 x=1 の両辺を cos 2 x で割ると Open the brackets. You then have three separate integrals. The first \int x^2dx is simple and equal to \frac {x^3}{3}. The second \int\tan^2xdx is also simple if you remember that \frac {d (\tan x)}{dx}=1+\tan^{2}x 2012/12/29 Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor.

The derivative of tan(x) tan (x) with respect to x x is sec2(x) sec 2 (x). 2sec2(x) 2 sec 2 (x) Free derivative calculator - differentiate functions with all the steps. Type in any function derivative to get the solution, steps and graph Example 2 Find the first derivative of f(x) = tan x + sec x Solution to Example 2: Let g(x) = tan x and h(x) = sec x, function f may be considered as the sum of functions g and h: f(x) = g(x) + h(x). Hence we use the sum rule, f '(x) = g '(x) + h '(x), to differentiate function f as follows f '(x) = sec 2 x + sec x tan x = sec x (sec x + tan x) A specialty in mathematical expressions is that the multiplication sign can be left out sometimes, for example we write "5x" instead of "5*x". The Derivative Calculator has to detect these cases and insert the multiplication sign. OK, time to improve our Homer J Simpson understanding of radiation safety.
