Question

if cot theta = 1 ; find the value of : 5 tan to the power 2 theta + 2 sin to the power 2 theta - 3

Answer 1

cot = 1

cos / sin = 1/1

sin = 1

tan = 1/ cot = 1/1 = 1

now putting value in eq.

$5tan {}^{2} + 2sin {}^{2} - 3$

$5(1) {}^{2} + 2(1) {}^{2} - 3$

7 - 3 = 4


Thanks

Answer 2

Answer:

3

Step-by-step explanation:

We knw that cot =base/perp.

i.e.base/perp. =1/1

Thus base=1x

Perp. =1x

By pyth. theo.

(Hypt) square = (1x) square +(1x)square

Hypt.= (2 (x square)) under root

Hypt. =x under root 2

5*(1/1 )square + 2*(x/x under root 2)square - 3

5+ 2* 1/2 - 3

5+1-3

6-3=3
