WebThe following two are not strictly required, but they might help as warm up and practice for this topic. Double integrals in polar coordinates; ... For x, we find that cos(θ) = x/R. Solving for x gives x = R*cos(θ). Substituting the value of R we found earlier gives x = r*sin(ϕ)*cos(θ). Weba² = b² + c² - 2bx All you need to do now is get rid of the letter x. This is done by using basic trigonometry in the triangle AND. Since CosѲ = adjacent/hypotenuse, then x can be expressed as: x = cCosA So the final step is to substitute x = cCosA into a² = b² + c² - 2bx: a² = b² + c² - 2bcCosA (just change x to cCosA)
