2 AnswersChemistry8 years agoMake the indicated trigonometric substitution and use fundamental identities and simplify the expression.?
1. √(16 - x^2) ; x=4sinΘ for -(pi/2) ≤ to Θ ≤ to (pi/2)
2. (x^2)/√(9 - x^2) ; x = 3sinΘ for -(pi/2) ≤ Θ ≤ to (pi/2)
3. x/√(25 +x^2) ; x=5tanΘ for -(pi/2) ≤ Θ ≤ to (pi/2)
4. √{[(x^2)+4]/x^2}/x^2 ; x=2tanΘ for -(pi/2) ≤ Θ ≤ to (pi/2)
I really need help on these I don't know what to do! And optionally, please give me some tips on how to improve, besides more practice problems, which I already know and have done.
