let B=base L=altitude and H=hypotenuse
At 900 B =0 and L=H,so sin 90=L/H=1 and cos90=0/H=0 tan 90 = L/B = L/0= infinite
At 00 L=0 and B=L so sin 0=0 , cos 0 =b/h=1 tan 0=L/B=0/b=0
Value of cot,sec and cosec can be found accordingly

LHS = [(1+sinA-cosA )/(1+sinA+cosA)]²
=[ (1+sin²A+cos²A+2sinA-2sinAcosA-2cosA)/(1+sin²A+cos²A+2sinA+2sinAcosA+2cosA) ]²
= [( 1+1+2sinA-2sinAcosA-2cosA)/(1+1+2sinA+2sinAcosA+2cosA)]²
= { ( 2(1+sinA) -2cosA(sinA+1) / [ 2(1+sinA) + 2cosA(sinA +1 ) ]}²
= { (2(1+sinA)[1 - cosA] /[2(1+sinA )(1 + cosA )] }²
= [ ( 1 - cosA ) / ( 1 + cosA ) ]²
= RHS

1 year = 365 days
A leap year has 366 days
A year has 52 weeks.
Hence there will be 52 Sundays for sure.
52 weeks = 52 × 7 = 364 days
366 – 364 =2 days
In a leap year there will be 52 Sundays and 2 days will be left.
These 2 days can be:
Sunday, Monday
Monday, Tuesday
Tuesday, Wednesday
Wednesday, Thursday
Thursday, Friday
Friday, Saturday
Saturday, Sunday
Of these total 7 outcomes, the favourable outcomes are 2.
Hence the probability of getting 53 days = 2/7

Given √2 is irrational number.
Let √2 = a / b wher a,b are integers b ≠ 0
we also suppose that a / b is written in the simplest form
Now √2 = a / b
⇒ 2 = a2 / b2
⇒ 2b2 = a2
∴ 2b2 is divisible by 2
⇒ a2 is divisible by 2
⇒ a is divisible by 2
∴ let a = 2c
a2 = 4c2
⇒ 2b2 = 4c2
⇒ b2 = 2c2
∴ 2c2 is divisible by 2
∴ b2 is divisible by 2
∴ b is divisible by 2
∴a are b are divisible by 2 .
this contradicts our supposition that a/b is written in the simplest form
Hence our supposition is wrong
∴ √2 is irrational number.

Given.... a 21 - a7 = 84
⇒ {a + (21 - 1 ) d} - {a + (7 - 1) d} = 84
⇒ a + 20d - a - 6d = 84
⇒14 d = 84
⇒d = 84/ 14
⇒ d = 6
Required Common Difference is 6.

A(2,3) B(-1,0) C(2,-4)
X1=2 X2=-1 X3=2
Y1=3 Y2=0 Y3= -4
Area of triangle = 1/2 {x1(y2-y3) + x2(y3-y1) + x3(y1-y2)}
= 1/2 {2(0-(-4)) + (-1) (-4-3) + 2(3-0)}
= 1/2 {8-(-7)+6}
= 1/2 {8+7+6}
= 1/2 × 21
= 21/2
