Answer:

Step-by-step explanation:

If (x - 5) is a factor of P(x) then P(5) = 0 ← Factor theorem

Given

P(x) = x³ - 5x² - x + 5, then

P(5) = 5³ - 5(5)² - 5 + 5 = 125 - 125 - 5 + 5 = 0

Since P(5) = 0 then (x - 5) is a factor of P(x)

Prove that 1/sin^2A -1/tan^2A= 1

Vika [28.1K]

Answer:

Step-by-step explanation:

$LHS =\dfrac{1}{Sin^{2} \ A }-\dfrac{1}{Tan^{2} \ A }\\\\\\ = \dfrac{1}{sin^{2} \ A}- \dfrac{1}{\dfrac{Sin^{2} \ A}{Cos^{2} \ A}}\\\\\\= \dfrac{1}{sin^{2} \ A } - \dfrac{Cos^{2} \ A}{Sin^{2} \ A}\\\\\\= \dfrac{1-Cos^{2} \ A}{Sin^{2} \ A}\\\\\\= \dfrac{Sin^{2} \ A}{Sin^{2} \ A}\\\\\\= 1 = \ RHS$

Hint: 1 - Cos² A = Sin² A
