You should definitely learn integration by parts.
Integration by parts becomes so useful, you'll even use it when you could do a simple u-substitution.
After integration by parts, I highly suggest learning trigonometric substitution. This helps you integrate expressions in a square root.
Answer:
Step-by-step explanation:
12 x + 4 y = 42 .............1
16 x + 8 y = 64 .............2
Eliminate y
multiply (1)by -2
Multiply (2) by 1
-24 x -8 y = -84
16 x 8 y = 64
Add the two equations
-8 x = -20
Answer:
the answer is 5
Step-by-step explanation:
Answer: It depends on the position.
Step-by-step explanation: Knights are better in closed positions and bishops are better in open positions. So they are better than the other in different scenarios.
Scientist look at various evidence like fossils, rocks, and glaciers to determine what it is like millions of years ago. Evidence like rocks, movement of the tectonic plates and glaciers can determine the landforms and climate of an area. Evidence like fossils, combined with the current knowledge of evolution and the climate at that time allows scientists to hypothesize what it looks like millions of years ago.
