(sin πx + cos πy)^9 = 34

Answer 1

could have sworn we did this already. no?

Answer 2

hey sorry my internet is acting up

Answer 3

yeah but we never finsihed it

Answer 4

oh the last job was just algebra, so solve that equation for

Answer 12

okiay leme punch that in

Answer 13

god i hope i did the algebra right because i did not check. is this a test?

Answer 14
