Gaurav Seth 4 years, 9 months ago

asinθ + bcosθ = c
taking square both sides,
(asinθ + bcosθ)² = c²
⇒a²sin²θ + b²cos²θ + 2absinθ.cosθ = c² --------(1)

Let acosθ - bsinθ = x
Squaring both sides
(acosθ - bsinθ)² = x²
⇒a²cos²θ + b²sin²θ -2absinθ.cosθ = x² ------(2)

Add equation (1) and (2),
a²sin²θ + b²cos²θ +2abinθ.cosθ + a²cos²θ + b²sin²θ -2absinθ.cosθ = c² + x²
⇒(a² + b²)cos²θ + (a² +b²)sin²θ = c² + x²
⇒(a² + b²)[sin²θ + cos²θ ] = c² + x²
⇒(a² + b²) = c² + x² [∵ sin²x + cos²x = 1 ]
⇒(a² + b² - c²) = x²
Take square root both sides,

Hence, acosθ - bsinθ =

Let a be the positive odd integer which when divided by 6 gives q as quotient and r as remainder.

according to Euclid’s division lemma
a=bq+r

a=6q+r

where , a=0,1,2,3,4,5
then,
a=6q
or
a=6q+1
or
a=6q+2
or
a=6q+3
or
a=6q+4
or
a=6q+5

but here,
a=6q+1 & a=6q+3 & a=6q+5 are odd.

Write all trigonometric ratios of angle A in terms of sec A

Posted by Parvathy Nair 4 years, 9 months ago

CBSE > Class 10 > Mathematics

1 answers

Yogita Ingle 4 years, 9 months ago

We know that,
sec A = 1/cos A
⇒ cos A = 1/sec A
cos²A + sin²A = 1
⇒ sin²A = 1 – cos²A
⇒ sin²A = 1 – (1/sec²A) (cosA= 1/secA)
⇒ sin²A = (sec²A-1)/sec²A

⇒sinA = √((sec²A-1)/sec²A)

⇒sinA = √(sec²A-1) ÷ (secA)............................(i)

sin A = 1/cosec A
⇒ cosec A = 1/sin A

⇒cosecA= secA ÷√sec²A-1 (from eq i)
Now,
sec²A – tan²A = 1
⇒ tan²A = sec²A + 1

⇒tanA = √sec²A + 1.....................................(ii)

tan A = 1/cot A
⇒ cot A = 1/tan A

⇒cotA = 1/√sec²A + 1 (from eq ii)

Aman Singh 4 years, 9 months ago

I assume you mean “IF a die is tossed three times, what is the probability of no fives?” Die #1 can do so with probability 5 / 6 (meaning, no fives). Ditto for #2, #3. Hence, the required probability is (5/6)*(5/6)*(5/6) = 125/216, which is almost 58%.
