+- 5)d) should have had both bounds modified
+ - when you have a negative outside, you can flip the bounds
+- 5)f) should have been a trig substituion of atan(u)
+- remember to use '='
+- use subscripts on different constants
+- don't use the same variable name twice
+- 6)e) you got the substition wrong when fixing the bounds, it should have been 2 and 1
+- you need to keep bounds when doing by parts, ie. convert to numbers asap!

+- see FIG1 for the "blackbox" solution the the problem
+ - no matter the order, you just solve for lambda
+ - in second order, this only works for homogenius equ (u = 0)
