What is the rectangular form of 6(cos(2250)+ i sin(2250)?

9514 1404 393

  -4.24264 -4.24264i

Step-by-step explanation:

Evaluate the sine and cosine terms and multiply.

   6(cos(225°) +i·sin(225°)) = 6(-√2/2 -i·√2/2)

   = -3√2 -i·3√2 ≈ -4.24264 -4.24264i

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
