If sinx=1/9, x in quadrant 1, then find (without finding x):
sin(2x)=
cos(2x)=
tan(2x)=?

Part 1)

Part 2)

Part 3)

Step-by-step explanation:

Part 1) Find sin(2x)

we know that

we have

Find cos(x)

Remember that

substitute

-----> is positive because angle x belong to the I quadrant

Find sin(2x)

we have

so

Part 2) Find cos(2x)

we know that

we have

so

Part 3) Find tan(2x)

we know that

we have

so
