The relationship between the cosine and sine graphs is that the cosine is the same as the sine — only it’s shifted to the left by 90 degrees, or π/2. The trigonometry equation that represents this relationship is: cosx= sin (x+π/2)
The graphs of the sine and cosine functions illustrate a property that exists for several pairings of the different trig functions. The property represented here is based on the right triangle and the two acute or complementary angles in a right triangle. The identities that arise from the triangle are called the cofunctionidentities.
Answer: d
Step-by-step explanation:
C. 5
The least possible degree of a polynomial with four turning points would be five.
Answer:7
Step-by-step explanation: the corners are half and there is 5 normal squares and 4 half squares so half of 4 is 2 and 5+2=7
