A convenient form of the equation that may be evaluated with a desk calculator is (4-2)L(λ)=(1.191066×108/λ5) (exp(1.43883×104/λT)−1)−1[W m−2E−1μm−1] where λ is entered directly in micrometers (μm). Figures 4-1, ...
However, to graph it, especially using a graphing calculator or computer program, we want to isolate y. x^2+y^2=(3+2x)^2 y^2=(3+2x)^2-x^2 y=±√((3+2x)^2-x^2 When our entire equation has been changed from rand to x and y, we can stop, unless asked to solve for y...
