Just to clarify, the first question is log with a subscript 2...I couldn't figure out how to write it like that on here
A) y = log2 [(e^(-x))*cos(pi x)]
My solution was -(1+tan(pi x))/ln2
B) arctan(xy) = 1 + (x^2)y
My solution was y(2x+2x^3y^2-1)/x(1-x-x^3y^2)
They are kind of complicated and I just want to make sure I have done them right. Did anyone else get these same answers or something different? Thank you!
