i cant find any symbols on this site so if its confusing please do tell.
sin[2(x-(pi/4))]=sq root2/2 for 0< x <2pi and for all feta (x=feta)
2(x-(pi/4))= pi/4 , 7pi/4
x-(pi/4) =pi/8 , 7pi/8
x = 3pi/8 9pi/8
based on the domain , only 3pi/8 fits.
for all feta = 3pi/8 +pi(n) , 9pi/8 + pi(n) where n is an element of the integers.
4cos(x+30degrees)+5=7 for 0<x<360 and for all feta (x=feta)
x+30 = 1.047197551
i dont know where to go from here
2sin[2(x-(pi/6))]=-sqroot3 for 0<x<2pi and for all feta (x=feta)
sin[2(x-(pi/6))] = -sqroot3/2
2(x-(pi/6))= pi/3 5pi/3
x-(pi/6) = pi/6 ,5pi/6
x= pi/3 and pi (both work)
for all: pi +pi(N) , pi/3 + pi(n) where n is an element of the integers.
3sin(x-1)=2 0<x<360 round to the tenth of a degree and for all feta (x=feta)
again im having problems with these decimal and degrees ones
and if you can check over the two i finished please and thank you , if i made mistakes please point them out even the obvious ones
i have a quiz tomorrow so if can someone PLEASE help me out thank you!
