Area Under a Curve. Find the area under the curve over the given interval of y=-cos(x); [3π/4,π]. To find the area under the curve we integrate the function over the given interval, so, we integrate y=-cos(x) over the interval [3pi/4,pi]. This gives us the area under the curve. This is a great Explanation of the Area Under a Curve. This is under the topic of Applications of Integration with this free online math video lesson. #calculus #freecalculusvideos #minutemath #areaunderacurve #areaunderthecurve #integrals #definiteintegral #mathhelp #calculushelp #lightboard #mathhelp #mathvideos Every Month we have a new GIVEAWAY that is FREE to Enter.

Derivative at a Value. Find the derivative of y=20/(x^2+5) at x=3. We learn how to find the derivative of y=20/(x^2+5) at x=3. We learn how to find the derivative of a function at a given value. In this video we review how to find the derivative of a function and what is the derivative of that function at a given value. We use common derivative properties to solve the derivative of the function. This is a great introduction into derivatives. This is under the topic of Applications of Differentiation with this free online math video lesson. #derivatives #derivativeatavalue #findthederivative #calculus #calculushelp #minutemath #minutemathhelp #onlinemathlessons Every Month we have a new GIVEAWAY that is FREE to Enter.
