Question

The acute angle x radians is such that x=k,whwere k is a positive constant.Express in terms of k
i)tan(pi-x)

Answer 1

sry its tanx=k

Answer 2

anyone?

Answer 3

There are tables that lay out these mappings. In this case
tan (pi-x) = -tan(x)

if tan(x)= k, then tan(pi-x) = -k

Answer 5

oh odd even properties thanks
