The number of girls who do wear a watch is double the number who doesn't but the number of boys who do not wear a watch is double the number who does if i tell you the number of girls in my class is double the number of boys can you tell me the number i teach |
|
Answer» Answer: Let number of girls who do not wear a watch = X, where x is any natural number. Number of girls who wear a watch =2 x ⇒Total number of Girls in the class= x + 2 x= 3 x Number of Boys who wear the watch = y,where y is any natural number. Number of Boys who do not wear the watch = 2 y ⇒Total number of Boys in the class=y +2 y=3 y It is also given that ,⇒ Total number of Girls = 2 × Total number of Boys → 3 x = 2 × 3 y → x= 2 y---------(1) Total number of students in the class = 3 x + 3 y =3 × 2 y+3 y-------(Using 1) = 6 y +3 y = 9 y, So, the number of students i teach will be multiple of 9. Which can be =9,18,27,36,45,....

Prove that (sin 2theta + cos 2 theta=1) |
|
Answer» We have to prove that sin² θ + cos² θ = 1. This formula can easily be proven by a right triangle! Consider a right triangle having an acute ANGLE θ, where the third angle will be 90° - θ. We get, sin θ = (OPPOSITE SIDE of θ) / (hypotenuse) sin² θ = [(opposite side of θ) / (hypotenuse)]² = (opposite side of θ)² / (hypotenuse)² And, cos θ = (adjacent side of θ) / (hypotenuse) cos² θ = [(adjacent side of θ) / (hypotenuse)]² = (adjacent side of θ)² / (hypotenuse)² And we remember the famous Pythagoras' Theorem. (opposite side of θ)² + (adjacent side of θ)² = (hypotenuse)² Now, LHS ⇒ sin² θ + cos² θ ⇒ [(opposite side of θ)² / (hypotenuse)²] + [(adjacent side of θ)² / (hypotenuse)²] ⇒ [(opposite side of θ)² + (adjacent side of θ)²] / (hypotenuse)² ⇒ (hypotenuse)² / (hypotenuse)² ⇒ 1 ⇒ RHS Hence Proved! |
