Answer:
False
Step-by-step explanation:
because trigonometric identities are true for ALL angles, whereas trigonometric equations are NOT true for ALL angles.
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
It is 
because you should use 
then just plug it in using
(1, 4) and (-2, -2).
That eliminates everything except the second one and the third.
So now we would find the b in the equation 
and that's all
Answer:
630
Step-by-step explanation:
10 times 21= 210÷2= 105
35×21=735-105=630
The polar coordinates are given by M(x, y), such tha x=rcos(teta), and y=rsin(teta), it was given M(5,5), so 5=rcos(teta) and 5=rsin(teta), the ratio gives us 5/5= cotan (teta), 1= cotan (teta), implies 1= tan(teta), so teta = Pi/4, let's find r
5=rsin(Pi/4)=r . sqrt(2)/2, so r =10/sqrt(2)=10sqrt(2)
finally the polar coordinates are (r, teta) = (10sqrt(2), Pi/4)
