By changing variables, integration can be simplified by using the substitutions x=a\sin(\theta), x=a\tan(\theta), or x=a\sec(\theta). Once the substitution is made the function can be simplified …

Mar 27, 2016 · #5x-15+2x=41# We can combine our variables on the left to get #7x-15=41# To get our constants on one side, we can add #15# to both sides. We now have the equation …

Solving concept. To solve a trig equation, transform it into one, or many, basic trig equations. Solving a trig equation, finally, results in solving various basic trig equations.

Integrating polynomial functions involves applying the reverse steps involved in differentiating polynomial functions. This typically involves using the power rule of integration.

We write #x^2+6x+9-9# If we group it this way: #(x^2+6x+9)-9# then we have a perfect square minus #9# And #(x^2+6x+9)-9=(x+3)^2-9# Solving an equation by completing the square: …

Dec 4, 2016 · int_40^41xsqrt(x-40)color(white).dx=406/15 >I=int_40^41xsqrt(x-40)color(white).dx We should apply the substitution u=x-40. This implies that x=u+40 and that du=dx. When …
