Sound waves travel in a repeating wave pattern. This represent graphically by sine and cosine functions. As trigonometric function is periodic therefore it use for sound wave. Similarly we use in wheel also for model function, because of rotation of wheel. Also use of periodic conditions.
Functions that behave differently based on the input (x) value. Piecewise Function. A function made up of 3 pieces as well as two pieces. Hence in some case piecewise function give discontinuous graph. Piecewise
Pythagoras identities are use to convert trigonometric ratio from one form to another. Also we use right angle triangle for conversion. Conversion of trigonometric ratio
This post is about Solution of questions of functions from past paper. In this post questions are from different paper from May 2013 to May 2023. By this post students will come to know variety of questions asked in previous year papers. The questions type in this post is calculator . www.cie.org.uk p
