Hello, I need some help resolving this problem of Trigonometric Identities. Use the reciprocal identities to resolve it SinA+cosA*cotA= cscA

Please see steps below

Step-by-step explanation:

Start by writing all trig functions in the equation in terms of their simplest forms using the two basic trig functions: :

Now work on the left side (which is the most complicated one), trying to simplify it using the properties for adding fractions with different denominators:

where in the last step we have used that the Pythagorean identity for:

Notice that we arrived at the expression: , which is exactly what appears on the other side of the initial equation/identity we needed to prove, so the prove has been completed.

i dont know sorry
