Find the value of integral ∫ C ( x + y + z ) d z , where C is parametrized by → r ( t ) = ⟨ 17 sin ( 5 t ) , 15 cos ( 5 t ) , 8 cos ( 5 t ) ⟩ for 0 ≤ t ≤ π .

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x

no its the same as every other grade
