Solve your math problems using our free math solver with stepbystep solutions Our math solver supports basic math, prealgebra, algebra, trigonometry, calculus and moreThe Chain Rule says the derivative of f (g (x)) = f' (g (x))g' (x) The individual derivatives are f' (g) = cos (g) g' (x) = 2x So d dx sin (x 2) = cos (g (x)) (2x) = 2x cos (x 2) Another way of writing the Chain Rule is dy dx = dy du du dxThere is no particular method that works for any combination of mathf(x) \cdot g(x)/math but your integral in particular is of the form math\int e^u du=e^uc/math We can then solve by letting mathu=02x/math and we can differentiate t

It is possible that the midpoint and/orTo find the answers, I can either work symbolically (like in the previous example) and then evaluate, or else I can find the values of the functions at x = 2 and then work from there It's probably simpler in this case to evaluate first, so f (2) = 2 (2) = 4 g (2) = (2) 4 = 6 h (2) = 5 – (2) 3 = 5 – 8 = –3Completing the square, f(x)=\frac{3}{4}(\frac{1}{x}\frac{1}{2})^2, so x=2 is a global minimum, and there is no minimum, absolute or relative, for x\gt 1 Completing the square, f ( x ) = 4 3 ( x 1 2 1 ) 2 , so x = − 2 is a global minimum, and there is no minimum, absolute or relative, for x > − 1

G(x) → "g of x" → "operation(s), g, applied to a given quantity or value , x" "g(x) = x1" tells you to simply subtract 1 from whatever xvalue is given g(5)= 5–1=4 g(6)= 6–1=5 g(9)= 9–1=8 g(x)=x1 f(x) → "f of x" → "operations, f, applied to a g #2 the letter which you use to label a function has no special meaning g (x) just identifies a function of x, in the same way as that f (x) does Using a "g" instead of an "f" only means the function has a different label assigned to it Typically this is done where you have already got an f (x), so creating another one would be f(x)*g(x) = (tan(x) 2/x)(x² 8) Apply FOIL in multiplying binomials Multiply the First terms, next is the Outer terms, then the Inner terms, and lastly, the Last terms = tan(x³) 8 tan(x) 2x²/x 2(8)/x Simplifying we get = tan(x³) 8 tan(x) 2x 16/x Now Multiplying it by x to remove the variable in the denominator and we get
