Trigonometry [ QUADRANTS]

EDEXCEL F. Pure Mathematics and IAL Pure Mathematics(P2,P3) syllabus include this topic. This video explains the steps of solving a trigonometric equations in different quadrants for a given range. Both positive and negative ranges are explained. Along with example math, derivation of the formula is also discussed. 0:00 - Signs of trigonometric functions and formula in each quadrant 3:30 - example 1 5:20 - example 2 7:15 - Formula for NEGATIVE RANGE 10:40 - Example 1 for negative range 14:45 - Example 2 for negative range 19:45 - Solving math using diagram ( derivation of formula ) - Positive range 25:28 - Solving math using diagram ( derivation of formula ) - Negative range #edexcel #pearson #puremath #furtherpuremath #IAL #ALEVEL #P3 #P2 #AS #A2 #Puremathematics2 #puremathmatics3 #trigonometry #quadrants #basicacuteangle #range #rotation #theta #anticlockwise #clockwise #doubleangle #positiverange #positiveangle #negativerange #negativeangle
