Question

(sinsquare30+4cotsquare45-secsquare60) (cosecsquare45×secsquare30)​

Answer 1

(sin²30 + 4cot²45- sec²60)(cosec²45×sec²30)........(1)

sin30 = 1/2 , cot45 = 1, sec60 = 2

cosec45= √2, sec30= 2/√3

put in (1)

= (1/4 + 4-4)( 2×4/3)

=(1/4)(8/3)

= 2/3

Answer 2

Step-by-step explanation:

HI.

HERE IZ UR ANSWER.

sin 30 = 1/2

cot 45 = 1

sec 60 = 2

cosec 45 = √2

sec 30 = 2/√3

sin^2 30 = 1/4

4 cot^2 45 = 4

sec^2 60 = 4

cosec^2 45 = 2

sec^30 = 4/3

(1/4 + 4 - 4) (2 * 4/3)

1/4 * 8/3

8/12

2/3
