Hello Calpal!
Use trigonometric identities to show:
a) Sin(t) / (1+cos(t)) = csc(t)
b) (sec2(t)-1) / sec2(t) = sin2(t)
c) Write an equivalent form of 1 / (1+sin(x)) without using fractions
First off a)
a)
sin(t) / (1+cos(t)) = csc(t)
sin(t) / (1+cos(t)) = 1 / sin(t)
sin²(t) = 1 + cos(t)
1- cos²(t) = 1 + cos(t)
cos²(t) = - cos(t)
t ∈ {± periodically π/2; π; 3π/2}
