sin²θ means (sin θ)², or the square of the sine of angle θ

Useful identities:

1. sin²θ + cos²θ = 1  

2. sin²θ = 1 − cos²θ

Explanation

Given:  

x = t  

y = m

We are to find:  

(y − x)ⁿ = ?

Step-by-step:

1. Substitute the values of x and y into the expression:  

   (y − x)ⁿ = (m − t)ⁿ

Explanation

A set of a finite number of elements is simply called a finite set

A finite set has a limited number of elements.

{1, 2, 3, ...., 999, 1000} - This set has a specific starting and ending point (1 to 1000), making it finite.

Explanation

letters in each group increase by +2 within the group and the first letters go +5 between groups.

• FHJ → F(6), H(8), J(10)

• KMO → K(11), M(13), O(15) (first +5)

• PRT → P(16), R(18), T(20) (first +5)

• Next first = 16 + 5 = 21 → U(21); then +2 → W(23); +2 → Y(25) ⇒ UWY.
