WebDec 21, 2024 · a. The variable θ represents the measure of the same angle in both the cylindrical and spherical coordinate systems. Points with coordinates (ρ, π 3, φ) lie on the plane that forms angle θ = π 3 with the positive x -axis. Because ρ > 0, the surface described by equation θ = π 3 is the half-plane shown in Figure 5.7.13. WebNotice that solving the equation directly for θ θ yielded two solutions: θ = π 6 θ = π 6 and θ = 5 π 6. θ = 5 π 6. However, in the graph there are three intersection points. The third …

Similarly, for the minus case, we equate a sin θ − b cos θ with the expansion of R sin (θ − α) as follows (note the minus signs carefully): . a sin θ − b cos θ ≡ R cos α sin θ − R sin α cos θ. Once again we will obtain (try it yourself!): `alpha=arctan\ b/a` and `R=sqrt(a^2+b^2)` Our equation for the minus case is: layachi hadji rate my professor
