81a^2x+9a^2y-90bx-10by

Alja [10]

1. Factor out 9a^2 from the expression
9a^2 x(9x+y) - 90bx - 10by

2. Factor out -10b from the expression
9a^2 x(9x+y) - 10b x(9x+y)

3. Factor out 9x + y from the expression
(9x+y)x(9a^2 - 10b)

Solution: (9x+y)x(9a^2 - 10b)

(1) Cos AcosecA=cot A

Mashutka [201]

Answer:

The Basic Identities are :

$cosec(A) = \frac{1}{ \sin(A) }$

$\tan(A) = \frac{ \sin(A) }{ \cos(A) }$

$\cot(A) = \frac{1}{ \tan(A) } = \frac{ \cos(A) }{ \sin(A) }$

So for this question :

$\cos(A)cosec(A) = \cot(A)$

$l.s.h = \cos(A) \times \frac{1}{ \sin(A) }$

$l.s.h = \frac{ \cos(A) }{ \sin(A) }$

$l.sh = \cot(A) \: (proven)$
