Question

evaluate: (sin90°÷cos45°) - (1÷cosec30°)

Answer 1

Answer:

0.914 is the answer

Step-by-step explanation:

0.914 or (2√2-1)/2

Answer 2

Answer:

Step-by-step explanation:

Sin 90= 1

Cos 45 = 1/root 2

Cosec 30 =2

Putting the values in the eq.

( 1 ÷ 1 / root 2 ) - ( 1 / 2 )

( 1 × root 2 ) - 1 /2

Root2 -1/2

2root 2 -1 /2 ( by taking lcm )
