#1)Pythagorean Trig Identities f(x)=sin(x)^2+cos(x)^2 show(f(x)) show(f(x).simplify_trig()) g(x)=f(x)/cos(x)^2 show(g(x)) show(g(x).simplify_trig()) h(x)=f(x)/sin(x)^2 show(h(x)) show(h(x).simplify_trig()) 
       





#2)Sum and Diff of 2 Angles Trig Identities var('y') f(x)=sin(x+y) show(f(x)) show(f(x).simplify_trig()) f(x)=sin(x-y) show(f(x)) show(f(x).simplify_trig()) f(x)=cos(x+y) show(f(x)) show(f(x).simplify_trig()) f(x)=cos(x-y) show(f(x)) show(f(x).simplify_trig()) 
       







#3)Double Angle Trig Identities f(x)=(1+cos(2*x))/2 show(f(x)) show(f(x).simplify_trig()) f(x)=(1-cos(2*x))/2 show(f(x)) show(f(x).simplify_trig())
