Question

if the value of [sin²30 degree+cos²30 degree] [sec²45 degree-tan²45 degree]​

Answer 1

Answer:

1

Step-by-step explanation:

(sin^2 30°+cos^2 30°)(sec^2 45°-tan^2 45°)

1*1=1 (sin^2A+cos^2A=1 or sec^2A-tan^2A=1)

Answer 2

Answer:

sin^2 30° is 1/4 , cos^2 30°is 3/4 , sec^2 45° is 1 and tan^2 45 is 1

then,

1/4+3/4+1-1=4/4=1

if their is × between them it will be 0

if - is there then also answer is 1
