Determine whether each expression below is always, sometimes, or never equivalent to sin x when 0° < x < 90° ? Can someone help me :(

If 90° < θ < 180° and cotθ = -1/3, then cscθ =

Recall the definition of a polynomial expression. find two polynomial expressions whose quotient, when simplified, is. use that division problem to determine whether polynomials are closed under division. then describe how theother three operations-addition, subtraction, and multiplication-are different from division of polynomials.

What are the equivalent ratios for 24/2= /3= /5.5=108/ = /15
