from the relation: (sin2(x) +cos2(x) =1 )
so , sin2(x)=1-cos2(x)
by subs. in the main eqn.
1-cos2(x) + cos(x) =1
by simplify the eqn.
cos(x) -cos2(x)=0
take cos(x) as a common factor
cos(x)* (1-cos(x))=0
then cos(x)=0 && cos(x)=1
cos(x)=0 if x= pi/2
& cos(x) = 1 if x = 0 , 2*pi
so the solution is x= {0,pi/2 , 2*pi}
Answer:
Which statements did you include in your answer?
Isolate sin(x) by adding 4 and taking the square root of both sides.
State that sin(x) = 2 or sin(x) = –2.
State that –2 and 2 are undefined values of the inverse sine function.
There are no solutions because –2 and 2 are not in the domain of the function.

First, simplify -y + 6 + 6y to 5y + 6. / Your problem should look like:
Second, subtract 6 from both sides. / Your problem should look like:
Third, subtract 9 - 6 to get 3. / Your problem should look like:
Fourth, divide both sides by 5. / Your problem should look like:
Answer as fraction: y =
Answer as decimal: 0.6
−y+6+6y=9
(−y+6y)+(6)=9(Combine Like Terms)
5y+6=9
Subtract 6 from both sides.
5y+6−6=9−6
5y=3
Divide both sides by 5.
5y/5=3/5
y=3/5
