MATHS PAPER 2 (GRADE 10)
Angle of depression -
Bar graph -
Angle of elevation -
Hypotenuse - Always across(opposite) 90 degrees
Usually abbreviated using the symbol 'r'
Reciprocal of sign
Opp/hypot - Cosec
Hypot/opp
Reciprocal of cos
Adj/hypot - Sec
Hypot/ adj
Reciprocal of tan
Opp/ adj - Cot
Adj/opp
Rationalizing the denominator - Taking the square root out of the denominator
Asymptote - Graph that get impossible close to.... But it never gets to ...
If A gets bigger...
(Amplitude) - Graph gets steeper
If A gets smaller...
(Amplitude) - Graph gets flatter
Q - Translates graphs up or down how many units
Angle A is and angle when they give us small 'a' is 42.7 m this means that a is -
Opposite side of angle A
AAA - You will only ever see in similarities!
Not congruent
Opposite - The side opposite the GIVEN (theta) angle (reference angle)
Adjacent - The side next to the GIVEN (theta) angle
, (Reference angle)
In trigonometry try and get - Unknown/ known
Because then it's easy to get unknown value
The values of the ratio stay........ If the angles does not change - The same
soh - cah - toa -
Silly old hippos can ample happily to other areas -
To find trigonometry ratios for any angle make sure your calculator is on DEG NOT ON
RAD OR GRAD -
Special angles - 0,
30,
45
60
90
Amplitude - The distance from the xbaxis to the maximum value
Period - The # of degrees the curve takes to repeat itself
Range - Set of y values
Decreasing function - When y value gets smaller as x or theta get bigger
Sin graph - Y=sinø
Max: 1
Min.:1
Sinø: positive = 0<ø<180
Period 360
Range -1<y<1 (equal toot greater/less than)decreasing function 90<ø<270
Cos graph - Max: 1
Min:-1
Period 360
Amplitude 1
Range -1<y<1
Decreasing function 0<ø<180
Tan graph - NO MAX OR MIN
verticals asymptote : ø=90& ø=270
Period 180
+= 0<ø<90 & 180<ø<270
