Question

show that 1 + sec theta by sec theta is equal to sin square theta by 1 - cos theta ​

Answer 1

Answer:

easily proved

Step-by-step explanation:

1 + sec theta by sec theta is equal to 1+cos theta

now

multiply num. and deno. by (1-cos theta)

Answer 2

LHS = 1+sec theta/ sec theta

= 1/ sec theta +1

= cos theta +1

RHS= sin^2 theta / 1- cos theta

= 1- cos^ theta / 1- cos theta

= (1+ cos theta × 1- cos theta)/ 1- cos theta

= 1 + cos theta = LHS
