Hello :
x= r cos<span>θ
y= r sin</span><span>θ
r = 4 and </span>θ =<span> −3π/4
cos( </span> −3π/4 ) = cos( 3π/4 ) = cos ( π - <span>π/4) = - cos (</span><span>π/4)= - </span><span>√2/2
</span>sin( −3π/4 ) = - sin( 3π/4 ) = - sin ( π - π/4) = -sin (π/4)= - √2/2
x = - 2 √2
y = - 2 √2
-3/2 , -3/7 , 0.75 , 2 i'm pretty sure this is right!
So ive done the math and if you add both mA & mB , mC would equal 10
6 unless it talks about positive to negative then its 2
an Integer is a while positive or negative number. so your integer would be 43
