There's two things I need help with for Pre-Calculus??????:

Find three very easy trig identities. With cos, sin and etc.

2. Remember to choose at least one with a rational expression (fraction) and one with a radical (square root).

3. Type just three very easy identities please. For only this part.

Part. 2

Express the inequality in interval notation: W > -8 O (-00, -8] O [-8, -00] O (-8, 00] O [-8, 00)Write the statement in terms of inequaes w is positive and less than 17 \fExpress the set in interval notation -10 9 8 -7 6 -5 4 3 2 -1 0 1 2 3 4 5 6 7 8 9 10 O (-5, 00] O [-5, 00] O [-5, 00) O (-5, 00)Express the set in interval notation -10 9 8 -7 6 -5 4 3 2 -1 0 1 2 3 4 5 6 7 8 9 10 O (-5, 00] O [-5, 00] O [-5, 00) O (-5, 00)Question 5 1 pts Express as an inequality: 2 is negative and greater than -9
