1.1 To work out the next number in
a sequence you have to learn
what numbers the sequence
goes up in.
1.1.1 1,3,5,7,9,.....,...... figure out the
next two numbers in the
sequence. To figure out the next
two numbers find out what the
sequence goes up in which is +2 so
the sequence is 1,3,5,7,9,11,13.
1.1.2 Figure out this sequence
2,5,10,17,26,....,....
1.1.2.1 The sequence is going up by +2.
To get from 2 to 5 is 3 and 5 and
then +2 to 3 so its +5 etc.
2 TRIGONOMETRY
2.1 To work out you have to find out the hypotenuse=h, opposite=o and
adjacent=a. You also have to figure out if it is sin=sine, cos=cosine,
tan=tangent. The hypotenuse is opposite the right angle of the shape, opposite
is the other angle.
