Answer:
Step-by-step explanation:
Add 
and 
on both sides.
Add or subtract like terms.
Divide 
on both sides.
is the independent variable now.
Tan(x)= sin(x)/cos(x), therefore, substitute sin(x)/cos(x) in the expression:
=(cos(x)(sin(x)/cos(x))-1)/cos^2(x)
simplify the 2 cos(x):
=(sin(x)-1)/cos^2(x)
Sin^2(x)+ cos^2(x)=1, sin^2(x)-1=- cos^2(x), substitute in the expression:
= -cos^2(x)/cos^2(x)= -1
Hi! I'm Jenny and I'm a mathematician! I'd love to help you with this problem! :)
Lets get started...
I'll write the equation out for you!
x + x(xx)
Put the value of x = 2 in the above expression we get,
2 + 2(22)
= 2 + 2(2 × 2)
= 2 + 2(4)
= 2 + 8
= 10
3*(3/4) = 9/4 = 2 (1/4)
