• AP program Use to solve and display arithmetic sequences. Enter known first term and common difference or any two terms of the sequence. Solves for terms and sums of AP's backwards and forwards.


• CMPLXNUM program Use to find roots and powers of complex numbers and convert between polar and rectangular forms.


• COPRIMES program Use to list the coprimes of n, between 1 and n.


• FACTORS program Use to list all factors of n (integer).


• FINDRULE program Use to find the relationship between a set of paired variables. Programs test for linear, quadratic, power, and exponential rules.


• GP program Use to solve and display geometric sequences. Enter known first term and common ratio or any two terms of the sequence. Solves for terms and sums of GP's backwards and forwards and also sum to infinity.


• GTHDECAY program Use to find exponential relationship in form y=a(r)^x from two points.


• HERON program Use to find semi-perimeter and area of triangle given all three side lengths.


• LATLONG program Use to solve distance problems on surface of earth given latitudes and longitudes.


• LINEAR program Use to find linear relationship in y=mx+c and ax+by=c forms, from (i) gradient and point or (ii) two points.


• NUMSEQS program Use to generate n terms of sequence of prime, square, triangle or Fibonacci numbers.


• PASCALCO program Use to list coefficients of row n of Pascal's triangle (0≤n≤336).


• PRIME program Use to find if n is prime. Returns smallest factor if composite.


• PRIMFACT program Use to find the prime factorisation of n.


• QUADSOLV program Use to convert between expanded, factored and completed square forms of any quadratic and find roots (even if complex).


• RIEMSUM program Store any function in Graph Y1 and then use Riemann sums to approximate the area beneath function (left, right, midpoint, trapezoidal or Simpsons strips).


• REPAY program Use to solve reducing balance loan problems, including creating an interest and repayment table in Stats.


• SLOPEFLD program Use to draw differential equation slope field. Enter dy/dx in Graph Y1 slot (*using X and/or Y) and set required V-Window first. Option to add a solution through a point. *NB Use x/θ/t or ALPHA X for X and ALPHA Y for Y.


• TRISOLVE program A must for all courses! Use to solve a triangle given various side and angle combinations.


• VCT~C2GO program Vectors, 2D. Calculate course to steer from A to B, given wind/current as a vector and the maximum speed of boat/plane. Bonus: return journey B to A!


• VCT~DIV program Vectors, 2D or 3D. Calculate position vector of point that divides interval AB in ratio m:n.


• VCT~PROJ program Vectors, 2D or 3D. Calculate scalar and vector projection of A onto B.


• VCT~TWO program Vectors, 2D or 3D. Enter two vectors and calculate sum, difference, magnitudes, dot and cross products.
