Question

if sinA= cos A find 2tan square a + sin square a+1

Answer 1

Answer:

354 is your answer....

Answer 2

Answer:

7/2

Step-by-step explanation:

tan a = sin a/cos a = 1

so, tan square a = 1^2 = 1

sin a = cos a => sin square a = cos square a

=> sin square a - cos square a = 0 ----1

now, sin square a + cos square a = 1 -----2

add 1 and 2

2 sin square a = 1

sin square a = 1/2

so,

2 (tan square a) + sin square a + 1 = 2 (1) + 1/2 + 1 = 7/2
