G=2,0 I have notes
If u want I can explain
The equation is ............... (it needed to be so many characters long)
390/1.5 = x - y
A -3 subtracted by 10 is -13 and it stays 2
Answer:
1-k^2
Step-by-step explanation:
tan A= sin A/cos A
(sin A)(cos A)(sin A/cos A)=(sin A)^2
(sin A) ^2 + (cos A) ^2= 1
(sin A) ^2=1-(cos A) ^2
(sin A)^2= 1 - k^2
