GRADES 11 AND 12 ARE HERE AlgebraPulse now covers Grade 7 through Grade 12. Everything new is free, like everything else that solves. Grade 11 • Function notation, inverses, domain and range • Exponential and logarithmic equations, change of base • Transformations named and justified • Radians kept exact in terms of pi • Identities, including proving one line by line • Trig equations over an interval, every solution listed • Sinusoidal functions: amplitude, period, phase shift, axis Grade 12 • Limits, and rates of change • Derivatives from first principles, then all four rules • Tangent lines and full curve sketching • Vectors in 2D and 3D, dot and cross products, projections • Permutations and combinations, exact to the last digit • Probability, binomial, hypergeometric and normal distributions • Statistics, correlation and least-squares regression Also new: an inline graph card under the answer, a grade-aware keypad that adds logs, radians, derivative and vector notation only where they belong, 31 more practice topics, 29 more lessons, and photo recognition that reads senior notation. FIXES FOR EVERY GRADE A long accuracy pass corrected how the working is presented across the whole app, including in Grades 7–10: • Linear equations and inequalities no longer show a step that undoes itself — a two-move question now takes two moves • The quadratic formula's denominator is bracketed correctly • Steps that only repeated the question have been removed • Values used in a step are now derived by an earlier step, so nothing arrives from nowhere • Consistent multiplication and number formatting throughout • Guidance cards no longer use the answer colour, so a refusal can never be mistaken for a result Every answer is still worked out on your device. No AI, no account, no internet.
