Verify ((csc^2x) + (2cscx) -3) / ((csc^2x) - 1) = (cscx+3) / (cscx + 1)

Solution:

Given that, we have to verify

Take the LHS

Use the following identity, for denominator

Therefore,

Numerator can be rewritten as:

Cancel the common terms

Thus, LHS = RHS

Thus proved

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)
