Transformation of cosine curve
- Dr.Lakshman Chaudhari
Drag the slider "a","b" and "c" and see what type of transformation occur.
1. Move slider ‘a’ in any direction ( a # o ) what type of transformation does this represent? 2. What happens when ‘a’ increate in positive direction? 3. What is the amplitude of function when a=1-5? 4. Does the amplitude change between a = 2 and a= 2? 5. Move slider b in any direction (b # o) What type of transformation does this represent? 6. When b = o then what type shape represent the function? 7. When b is increased in positive direction the function are stretched / compressed? 8. Does the period change between when b is positive and b is negative? 9. Move slider ‘c’ in any direction what type of transformation does this represent? 10. Write the function when a = 2 , b = 1.5 and c= 2
