I was given this homework problem, but I'm not even sure what it's asking me to do. Find all points on the curve y=8tanx, [-π/2,π/2], where the tangent line is parallel to y=16x...
the whole question asks: State the domain and range of the function. (Enter your answers using interval notation.) f(x) = 2x^2 − 4x − 7. the domain is all real numbers, but i don't know what...
If 270º <x< 360º , show that √(2+√(2+2cosx)) = 2 sin x/4. Thank You! :)
lim cosθ-(1/√2)/(θ-π/4) θ→π/4 I rewrote θ as h so I have lim which is cosh-(1/√2)/h-(π/4) ...
