If the axes are rotated through an angle , the coordinates of the point in the new system are
- A
- B
- C
- D
Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
If the coordinate axes are rotated through an angle θ, then a point P(x, y) will have co-ordinate P(x', y') Where x'=xcosθ+ysinθ and y'=ycosθ-xsinθ Here, x, y=22, -32 and θ=45° Now, x'=22cos45°-32sin45°…
