Question

If iCAP-jCAP , iCAP+jCAP encloses a triangle then find its area ?​

Answer 1

Explanation:

begin mathsize 14px style v with rightwards arrow on top space equals space 2 i with hat on top space plus space 3 j with hat on top space space space semicolon space space space space a with rightwards arrow on top equals i with hat on top space plus space j with hat on top space end style

It is assumed that vector-v is initial velocity and vector-a is acceleration vector .

Also it is assumed that it is required to find the rate of change of direction of instantaneous velocity vector V at any instant t

Hence velocity V at any instant t is begin mathsize 14px style V with rightwards arrow on top space equals space v with rightwards arrow on top space plus space a with rightwards arrow on top t space space equals space open parentheses space 2 i with hat on top space plus space 3 j with hat on top space close parentheses space plus space open parentheses space i with hat on top space plus space j with hat on top space close parentheses t space equals space open parentheses 2 plus t close parentheses i with hat on top space plus space open parentheses 3 plus t close parentheses j with hat on top space end style

if θ is the angle made by the vector with x-axis is considered as direction ,

then direction of vector in terms of tangent of the angle θ is given by

Answer 2

Answer:

Easy you can do this just remember the formula for calculating the area of triangle 1/2.a×b , where a and b are the 2 vectors given find their cross product . you will get your ans...
