Prove that ,tanA+sinA/tanA-sunA=secA+1/secA-1​

Answer»

ANSWER:

LHS = RHS

Step-by-step explanation:

Given that,

RHS = \sf{\dfrac{<klux>SECA</klux> \ + \ 1}{secA \ - \ 1}}

LHS = \sf{\dfrac{tanA \ + \ sinA}{tanA \ - \ sinA}}

We know that

\boxed{\sf{tanA = \dfrac{sinA}{cosA}}}

\boxed{\sf{sinA = \dfrac{1}{cosecA}}}

Substituting these VALUES in LHS

\sf\dfrac{\dfrac{sinA}{cosA} + \dfrac{1}{cosecA}}{\dfrac{sinA}{cosA} - \dfrac{1}{cosecA}}

On TAKING LCM we get,

\sf\dfrac{\dfrac{sinA \times cosecA + cosA}{cosA \times cosecA}}{\dfrac{sinA \times cosecA - cosA}{cosA \times cosecA}}

On Cancelling cosA × cosecA we get,

{\sf\dfrac{sinA \ \times \ cosecA + cosA}{sinA \ \times \ cosecA - cosA}}

We know that,

\boxed{\sf{sinA \times cosecA = 1}}

{\sf\dfrac{1 + cosA}{1 - cosA}}

We know that  

\boxed{\sf{cosA = \dfrac{1}{secA}}}

\sf\dfrac{1 +\dfrac{1}{secA}}{1 - \dfrac{1}{secA}}

On taking LCM we get,

\sf\dfrac{\dfrac{secA + 1}{secA}}{\dfrac{secA - 1}{secA}}

On Cancelling secA we get,

LHS = \sf\dfrac{secA + 1}{secA - 1}

RHS =  \sf{\dfrac{secA \ + \ 1}{secA \ - \ 1}}

∴ LHS = RHS

Hence PROVED.

Tanθ/1−cotθ+cotθ/1−tanθ=1+secθ⋅cosecθ

Answer»

\huge\bold{HEY:)-}

============

⭐⭐⭐⭐⭐⭐ ⭐ ⭐ ⭐ ⭐ ⭐ ❤❤❤⭐⭐⭐⭐ \\ \\ \\ \\ \\

LHS = tanθ/(1 - cotθ) + cotθ/(1 - tanθ)

= tanθ/(1 - 1/tanθ) + (1/tanθ)/(1 - tanθ)

= tan²θ/(tanθ - 1) + 1/tanθ(1 - tanθ)

= tan³θ/(tanθ - 1) - 1/tanθ(tanθ - 1)

= (tan³θ - 1)/tanθ(tanθ - 1)

= (tanθ - 1)(tan²θ + 1 + tanθ)/tanθ(tanθ - 1)

= (tan²θ + 1 + tanθ)/tanθ

= tanθ + cotθ + 1

= sinθ/cosθ + cosθ/sinθ + 1

= (sin²θ + cos²θ)/sinθ.cosθ + 1

= secθ.cosecθ + 1

= 1 + secθ.cosecθ = RHS

Factorise a square + b square minus 2 into a b minus AC + BC​

Answer»

a^2 + b^2 - 2(AB - ac +BC)

= a^2 + b^2 - 2ab + 2ac - 2BC

= (a- b)^2 + 2ac - 2bc [ we know that a^2 + b^2 - 2ab

= (a-b)^2]

= (a- b)^2 +2c (a-b)

find the value of a and b for which the following system of linear equation has infinite number of solution 2x-3y=0 ; (a+b)x-(a+b-3)y=4a+b​

Answer»

Answer:

a1/a2=b1/b2=c1/c2

2/(a+B)=-3/(-a-b+3)=7/4a+b

2/a+b=7/4a+b

8a+2b=7a+7b

1a-5b=0.....1

-3/-a-b+3=7/4a+b

-12a-3b=-7a-7b+21

-5a+4b=21....2

1*-5

-5a+25b=0

1-2

-5a+25b=0

-5a+4b=21

21b=-21

b=-1

substituting the VALUE of b in 2

therefore a=5

therefore a and b satisfies EQUATION a+5b=0

5-5=0

If x²-3x+2 divides x³-6x²+ax+b exactly,then find the value of a and b.​

Answer»

Answer:

11, -6

Step-by-step EXPLANATION:

x²-3x+2 has two roots 1,2

as x²-3x+2 DIVIDES x³-6x²+ax+b  ,1 and 2 are ALSO roots of x³-6x²+ax+b

SUBSTITUTE 1 in x³-6x²+ax+b

==> 1-6+a+b=0

==>a+b=5                             (1)

substitute 2 in x³-6x²+ax+b

====>8-24+2a+b=0

===>2a+b=16                     (2)

solving 1,2

a=11,b=-6
