Question

sin²°38° + sin²52° + sin²30° - tan²45° का
मान किसके बराबर है ?​

Answer 1

Answer:

1. sin square 38 + cos square 38 + sin square 30 - tan square 45
2. 1 - 1 + sin square 30
3. (1/2) whole square
4. 1/4 ( answer)

Answer 2

Answer:

Step-by-step explanation:

=>sin² 38° + cos² 38 + 1/2 - 1

=>1+1/2-1                  - using  identity [ sin²a + cos²a =1]

==>>>ans: 1/2
