1. Write the sum as a product: cos (16.8x) - cos(12.6x) = ?
Please answer all of the following math problem ? Thank you
1. Write the sum as a product:
cos (16.8x) - cos(12.6x) = ?
2. Write the sum as a product:
sin (24.8a) + sin(5.4a) = ?
3. Write the product as a sum or difference:
12 sin(13s) cos (11s) = ?
4. Use the product to sum formula to fill in the ❓ in the identity below:
sin(4x) cos(3x) = 1/2(sin(❓x) + sin(❓x))
5. Use the product to sum formula to fill in the ❓ in the identity below:
sin(9x) cos(3x) = 1/2(sin(❓x) + sin(❓x))
6. Solve sin(x) = 0.67 on 0 greater than x < 2 pie. There are two solutions, A and B, with A < B. Give your answers accurate to 3 decimal places. Watch the mode on your calculator, they are asking for radian solutions.
A= ?
B = ?
7. Solve cos(x) = -0.61on 0 greater than x < 2 pie. There are two solutions, A and B, with A < B. Give your answers accurate to 3 decimal places. Watch the mode on your calculator, they are asking for radian solutions.
A= ?
B = ?
