Answer:
See below ~
Step-by-step explanation:
<u>Identities Needed</u>
- sec a = 1 / cos a
- cosec a = 1 / sin a
- cot a = 1 / tan a
<u />
<u>Proving</u>
- (sec²a)(cosec²a) = tan²a + cot²a + 2
<u>Taking the LHS</u>
- sec²a x cosec²a
- 1/cos²a x 1/sin²a
- 1/(sin²a)(cos²a) -(Equation 1)
<u>Taking the RHS</u>
- tan²a + cot²a + 2
- tan²a + cot²a + 2(tana)(cota)
- (tana + cota)²
- (sina/cosa + cosa/sina)²
- (sin²a + cos²a / sinacosa)²
- (1/sinacosa)²
- 1/(sin²a)(cos²a) -(Equation 2)
∴ Equation 1 = Equation 2
∴ <u>LHS = RHS</u>
Hence, proved.
Answer:
Order of operations tells you to perform multiplication and division first, working from left to right, before doing addition and subtraction. Continue to perform multiplication and division from left to right. Next, add and subtract from left to right.
