# Csctheta #

Uitleg:

# Sectheta = 1 / costheta #

# Csctheta = 1 / sintheta #

# Sin ^ ^ 2thetacosthetacsc 3thetasectheta = sin ^ 2thetacostheta1 / (sin ^ 3theta) 1 / costheta #

# Costhetaxx1 / costheta = 1 #

# Sin ^ 2thetaxx1 / sin ^ 3theta = 1 / sintheta #

# 1 / sinthetaxx1 = 1 / sintheta = csctheta #
