Question 2 / Vraag 2 (2.1) Use the sum and difference identities on the last page to find tan (127π), leaving the answer in the form a+bc, where a,b,c∈Z. (Hint: 127π=4π+3π. ) Gebruik die som- en verskil-identiteite op die laaste bladsy om tan (127π) en laat die antwoord in die vorm a+bc, waar a,b,c∈Z. (Wenk: 127π=4π+3π.) (2.2) Sketch the graph of the function y=3cos4t, showing the amplitude and period. Skets die grafiek van die funksie y=3cos4t en toon die amplitude en periode aan.
