you can relate the equation x²+y²=r² and the identity cos²(x)+sin²(x) = 1 to each other to try guess what the graph may look like

#

if you have a circle radius r and an angle theta
x = rcostheta
y = rsintheta

#

or find the cartesian equation by using pythag identity

sometimes yh

#

inaner can u help with decision now

rich moss
#

u have sin and cos and u wana try make into one so
u try use sin^2x+cos^2x = 1

#

if u were really stumped

#

pick nice values of theta

#

so 60,45,90 , 0

#

and just try plot it

#

dont matter
