Mathematically speaking, how do we know the area inside the P-V curve is equal to the work done by the gas? The filament of a 60W lightbulb is at 2.8 kK. What's the surface area of the filament? Find the area enclosed by the curve y=sinx and the x-axis between x...
For what values of the numbers a and b does the function {eq}f(x)= axe^{bx^2} {/eq} have the maximum value f(1)=7?Derivatives:Recall that a derivative gives us the slope of a curve at a point. So places where we have extrema are often pl...
