WebLooking back at relationship (1), we see it is only a half plane because ρ sin ϕ cannot be negative. Constant ρ Most people don't have trouble understanding what ρ = 3 means. It is the sphere of radius 3 centered at the origin. In general, the surface ρ = constant is a sphere of radius ρ centered at the origin. WebThe hypotenuse will be the larger value (√2) and the other two sides will both be 1. This makes sense, especially when we plug these values into the Pythagorean theorem: a^2 + b^2 = c^2 1^2 + 1^2 = (√2)^2 1 + 1 = 2 2 = 2 So now we have our sides, so we can very easily find sin/cos/tan values. sin = O/H = 1/√2 cos = A/H = 1/√2 tan = O/A = 1/1 = 1
